[gentoo-dev] [PATCH 00/21] gen_usr_ldscript: migrate away from a sep-/usr by default

[gentoo-dev] [PATCH 00/21] gen_usr_ldscript: migrate away from a sep-/usr by default

[Mike Frysinger]

To make forward progress on bug 417451, introduce a new sep-usr eclass
that will hold all logic related to having a separate /usr.  For now,
this is just the gen_usr_ldscript function and a new USE=sep-usr flag.

All ebuilds that call gen_usr_ldscript today will migrate to this and
will allow people to move away from installing things into /.  For the
systems that want to have a split-/usr partition, they can turn on this
USE flag across their system.

This also allows us to mask the flag on many targets where it doesn't
make sense (like most prefix setups) and where we don't want to support
it at all.

[gentoo-dev] [PATCH 01/21] sep-usr.eclass: new eclass to hold gen_usr_ldscript and related logic #417451

[Mike Frysinger]

This is mostly a copy of the func as it exists in the toolchain-funcs
eclass, but with some of the initial logic shifted to USE=sep-usr.
Once all ebuilds have switched over to this eclass, we can drop it
from the toolchain-funcs eclass.  In the meantime, make sure this is
inherited last.

Good idea, thanks. I'm not 100% convinced it is worth a useflag (instead of 
e.g. a make.defaults variable that one can override in make.conf), but why 
not.

Your patchset seems to be missing some ebuilds in that regard: expat and 
sys-freebsd/* come to mind.

It should be noted that, unless I missed something, the default settings 
will *not anymore* allow sep-usr after this patchset (sep-usr useflag will 
be disabled). This should be advertised more (a news item?) or simply 
sep-usr added to make.defaults. The latter will also enable busybox's 
sep-usr support.

i did not do a full migration as i got bored, but i did do enough to show
it in action.  the current method does not require all be converted at the
same time though, so it can be left up to maintainers of relevant packages
to do the change over themselves.

the patchset allows for some targets (notably Linux systems) to control
whether the flag is enabled.  it is turned off by default and i think
that's the behavior we want.  i have not forced enabled it for any target
but maybe the prefix/darwin guys will want to do that.

i dont think anybody expects you to post tree-wide conversion patches to 
-dev ml :)

but i also dont think it is a good idea to leave the toolchain-funcs 
version around, and if you want to drop it, you'll have to fill bugs to let 
ppl know, which is probably more work than adding 8 chars to an inherit 
line that can be automated

not sure if this was phrased as such, but I seem to recall a council 
decision stating that separate /usr should be made easy to users unless 
this causes serious issues; thus, no, I don't think that is the behavior we 
want :)

sure -- backwards compat won't be dropped until we're confident everyone
has migrated over

pretty sure the decision was that it's not required to be supported.  and
regardless of that, i don't see the default behavior of being off as being
contra "easy to use".

lemme look it up for you then:
https://wiki.gentoo.org/wiki/Council_decisions

systems with separate /usr should be supported. However, users shouldn't be 
constrained from using software which doesn't support that. -- 04/2012 
meeting

The council has voted in favour of a separate /usr being supported
(5 yes, 1 no vote).

>  and
> regardless of that, i don't see the default behavior of being off as being

but you're right there, it doesn't make it hard to use, just not working 
out of the box, which is already debatable; however, with eudev being the 
default I don't think there is anything preventing it atm with a default 
setup, but i might certainly stand corrected there

not really.  a simple grep in the tree for the single func being dropped
is fairly trivial.

"being supported" != "enabled by default".  so no, i still don't see any
requirement in anything you've cited that this be turned on by default.

you're right, but you know, before you claimed the contrary of what was

i see no significant number of people clamoring for this as the default.
the bug that started this has everyone on board for changing the default.
it's really no different either from the install process today: a stage3
cannot be unpacked & booted directly.  a user must configure it before it
can actually be used.  if that means enabling USE=sep-usr, then so be it.
there's no reason to force this legacy behavior on the majority of people
when a split-/usr is uncommon.

yes; I also tend to think fedora's usr move is what makes most sense 
nowadays, but that'd go against council

what's the reason not to force it? saving 10kb from ldscripts out of a 1Gb 
typical desktop install ? doesnt seem like a reason for disabling it either

No, it wouldn't. We made a decision in 2013 (I'll have to find it) that
separate /usr should only be supported via initramfs; there is also a
news item warning that if you are not using initramfs and you have
separate /usr your system will be unbootable in the future.

Here are the latest council decision on the matter [1] and news item [2].
At this point, if anyone who has split /usr isn't using initramfs,
they are operating on borrowed time.

I would agree, since it has been so long, that we should do another news
item, but once the news item is done and we give a firm date, I think
we should just kill off gen_usr_ldscript.

The /usr merge is a separate issue, which I agree with as well, but that
was never brought to council, and it is controversial in the Gentoo camp
because some folks claim fhs doesn't allow it.

Good then, thanks. I didn't remember this one and failed to see it when 
looking at council decisions. I assume there's nothing preventing disabling 
gen_usr_ldscript by default then. Apologies to Mike for being annoying on 
this one :)

I also assumed making eudev default was a step in having sep-usr work by 
default as the initial issue was brought up by udev, but that's flawed 
reversed logic.

Killing it is too violent IMHO: It doesn't provide much gain and makes it 
very annoying to get sep-usr working afterwards. I think current proposal 
to make it optional is the best option.

Getting a bit OT, but can you explain in what ways it violates fhs ?
What worries me more about /usr merge is that I've never seen a plan for 
it. I think it'd be necessary to have portage gain some intra-package 
collision check (e.g. a package installing /bin/foo and /usr/bin/foo should 
be reported), which would then allow building /usr-merged stages, but the 
main issue for me is how to migrate installed systems properly.

FWIW, I actually run a (reverse) merged /usr here, along with the bin/sbin 
merge.

Obviously it's symlinks as the packages still install where they will 
install, but:

/usr -> .
/sbin -> bin

As a result I have the following "semi-flattened" directory structure 
directly on /, including everything that would normally be under /usr:

/bin
/boot
/dev
/etc
/games -> .
/home
/include
/lib -> /lib64
/lib64
/libexec
/local
/media
/proc
/root
/run
/sbin -> bin
/share
/src
/srv
/sys
/tmp
/usr -> .
/var
/x86_64-pc-linux-gnu

(That excludes some unrelated additional changes of my own, again mostly 
to shorten paths, such as /home actually being /home -> /h (/h being the 
actual mountpoint for what would normally be /home in fstab), /local, 
what would be /usr/local, actually being /local -> /l, and /var/log -> /
lg (with /lg being a mountpoint as well, isolating logs and keeping 
runaway logging from creating havoc on anything but /lg itself).)


You will be glad to note that portage has in fact been smart enough to 
avoid symlinks overwriting the files they would normally point at for 
quite some time -- in fact, I specifically asked about this on the 
portage list before I tried it myself.  So that's not a problem at all.

There are, however, occasional bugs when specific packages try to clean 
up old versions and end up deleting the new version instead, because they 
don't dereference symlinks to a canonical path before they do the rm.  
One current example of that is gcc-config:

[Bug 554334] sys-devel/gcc-config pkg-postinst rm -f /usr/sbin/gcc-config 
breaks when using /usr/sbin->bin symlinks

https://bugs.gentoo.org/show_bug.cgi?id=554334

The result of that bug is that gcc-config deletes its own executable.  
However, it's worth repeating that the bug is because the ebuild itself 
executes rm -f on an arbitrary path without resolving both it and the 
canonical path of its executable and comparing them -- it's not a bug in 
portage itself, portage itself behaves correctly in terms of resolving to 
canonical paths.

Fortunately for me, while that bug has been open for 8 months+, my sync 
script can automatically patch ebuilds using patches in /etc/portage/
patches.ebuild, much like the portage implementation of eapply_user 
patches sources with patches found in /etc/portage/patches.  So now I've 
worked around that bug by patching out the offending rm line in the 
ebuild.  Hey, when eight months and counting later a critical bug in a 
toolchain package remains open, a good gentooer tends to find 
workarounds.  What can I say?


Packages that use cmake can sometimes have issues too, depending on the 
version of cmake, as it apparently doesn't always properly resolve to 
canonical paths.  As I'm a kde5/plasma user and one such affected package 
has been baloo, a plasma dependency, that has been a headache for me.  
But being a USE=-semantic-desktop user in the kde4 era, I didn't really 
want baloo on my system anyway, so rather than spend the time researching 
how to fix the bad cmake/symlinks interaction, I was motivated to 
research killing the baloo deps instead, and ultimately source-patched 
(as opposed to ebuild-patched, as I did gcc-config) the two plasma 
packages requiring it to kill the baloo-based modules.  With the sources 
patched to no longer require baloo, I simply placed a baloo null-package 
in my overlay (the other alternatives would be package.provided, but 
that's deprecated, or to use the ebuild patching sync-script mentioned 
above to delete the baloo-deps in the ebuild) to fill the ebuild 
dependency, and that's what I'm running with today.

The merged /usr and bin/sbin cmake related bugs I've filed are:

cmake/baloo: https://bugs.gentoo.org/show_bug.cgi?id=561956

(Unrelated to /usr or bin/sbin merge but mentioned above as my resolution 
for the cmake/baloo bug, the no-baloo patches bug:
https://bugs.gentoo.org/show_bug.cgi?id=578664 )

Older cmake/libraw bug, resolved with newer versions of one or the other: 
https://bugs.gentoo.org/show_bug.cgi?id=532426

Older plasma5 plasma-desktop bug that kept the plasma5 desktop from 
coming up properly, as I was switching to it from kde/plasma4, so I'm not 
sure if it was a regression from earlier plasma5 or not.  Fixed in 
current plasma: https://bugs.gentoo.org/show_bug.cgi?id=570210

IIRC I had one other /usr or bin/sbin related bug a couple years ago 
shortly after I first did the merge, but IDR what it was well enough to 
search my bugmail archive for it and get a link.

With nearly 1000 packages installed and 316 listed in various sets found 
in my world_sets file, that's all the /usr and bin/sbin merge bugs I've 
seen in what I'd guess to be two years plus of running merged, so it's 
obviously not a common problem at all.

And of course if gentoo more officially supported the /usr and bin/sbin 
merges, I'd have probably never seen half those bugs, as they'd have been 
caught before I ever saw them, even on ~arch.  Tho of course there'd be 
other bugs filed by others, for packages I don't have installed here.

But a merge-related bug is still relatively rare.  It's gotta be less 
than half the bugs I file and I'd guess 20% or less, and my setup is rare 
enough that were it mainstream, most users, certainly by stable, would be 
unlikely to ever see a /usr or bin/sbin merge related bug at all.

Seems like a decent idea.

Before this flag gets added, should we define some bounds? I just
don't want to see this flag get abused by using it to move other files
around randomly, like moving things from /bin to /usr/bin, etc.

So the sep-usr flag will be disabled by default? That's going to
trigger a change from the current state, and will definitely need to
be announced.

i think we can scope it currently for libs (and any data files they need),
but i don't see it being a bad thing to leverage it for /bin progs.

unless you symlink /bin to /usr/bin, moving binaries around has wider

no valid package will be affected.  if you're hardcoding `/bin/foo`, then
you're doing it wrong already and that's your fault.

there are exceptions for a few very well known programs, but a few shebangs
does not mean supporting `/bin/cut` or `/bin/kmod` is required.
