[gentoo-user] How can I prevent gentoo-sources being installed?

[gentoo-user] How can I prevent gentoo-sources being installed?

[Jarry]

Hi Gentoo-users,
what an unpleasant surprise awaited me today when I tried to
update my systems: gentoo-sources want to be installed everywhere!
-------------------
  # emerge --pretend --update --deep --newuse --verbose world

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N     ] sys-devel/bc-1.06.95  USE="readline -libedit -static" 
284 kB
[ebuild     U  ] app-admin/eselect-python-20111108 [20100321] 64 kB
[ebuild  N     ] sys-kernel/gentoo-sources-3.7.10:3.7.10  USE="-build 
-deblob -symlink" 68,335 kB
[ebuild  N     ] virtual/linux-sources-0  0 kB
[ebuild   R    ] sys-apps/kmod-12-r1  USE="tools zlib -debug -doc -lzma 
-static-libs" KERNEL="(linux%*)" 0 kB

Total: 5 packages (1 upgrade, 3 new, 1 reinstall), Size of downloads: 
68,682 kB
-------------------

Why in the heavens name should be gentoo-sources pulled in as
dependency of whatever? I have 6 nearly identical machines, and
use only one for kernel compilation, so why should I now have
gentoo-sources on every system? Can I somehow prevent it?

As a dependency of virtual-sources, which is probably pulled in by kmod.
Adding --tree would have told you for sure.

You may get away with adding gentoo-sources to package.provided.

Thanks, this works (never heard of this file before). But there
is one small problem: no wildcards are allowed, so whenever new
sorces come I'll have to edit package.provided again, and again...

BTW why should kmod depend on kernel-sources? Or even better, why
should be kmod installed, if I have static (non-modular) kernel?

No, that's not true. Here's the quote from the man page:

   Portage will not attempt to update a package that is listed here
unless another package explicitly requires a version that is newer than
what has been listed. Dependencies that are satisfied by
package.provided entries may cause installed packages satisfying
equivalent dependencies to be removed by emerge(1) --depclean actions
(see the ACTIONS section of the emerge(1) man page for more information).

Because your use case is not standard. The normal situation for users
with kmod installed (and you have already kmod installed, since in
your --pretend run appears as to be reinstalled) is for them to use
kernel modules. The developers cannot handle every possible
combination of configurations, so defaults are set for the least weird
cases, or the common case even.

Your setup is not the norm; therefore, it depends on you to keep it as
you like it.

The case is actually quite common; Linux *sources* are only needed for
building kernels on the local machine (and - if used - additional
modules like nvidia-drivers).
Anyone who does not build the kernel on the local machine, e.g. taking
stock kernels from Debian/Fedora/..., kernel provided by
netboot/openvz/Xen domUs or build them remotely will almost never need
linux-sources installed.

BTW this will also add full kernel sources to all stage3 archives,
increasing their size quite significantly.

Felix

Stage 3 archives only contains necessary packages for which there is no
choice. They don't include a cron daemon or a system logger for that
reason, so they won't include kernel sources.

But what are kernel-sources good for after kernel has been compiled?
They take some disk-space (~700MB in my case!), so I think it is
quite logical to compile kernel, install & test it, and after that
get rid of kernel-sources.

And I still do not know what does kmod need from kernel-sources.
Some part of kernel source-code? Strange is, up to now kmod was
satisfied even without kernel-sources...

I know some other packages look for kernel-sources, but issue
only warning if can not found any (i.e. udev). But why does
kmod need kernel-sources so badly it pulls them as dependency?

Even if it is "quite common" (which I doubt) is not the norm. The
Gentoo Handbook[1] and Gentoo Linux Kernel Guide[2] only discusses one
method to get  kernel which you can boot: installing one of the
several sources packages available under sys-kernel/*-sources, and
configuring it manually or via genkernel.

Yeah, and you can install the kernel that your cousin Billy compiled
for you. Neither of those methods are the norm, as covered by the
Gentoo documentation, and therefore if you use those methods, you are
on your own.

Which has nothing to do with the topic at hand.

It doesn't; this is just a side effect of inheriting linux-mod.eclass.
The developer involved is trying to come up with a better solution
right now.

AFAICT stage3 archives include everything of @system.

virtual/dev-manager usually pulls in udev, which might pull in kmod
(depending on USE flags) and virtual/modutils is part of system, which
by default uses kmod.
So kmod is part of system and it then requires virtual/linux-sources as
a dependency, so they are now part of system as well.

That wasn't the case some days ago, and IMHO linux-sources should not be
part of @system in the future.

Felix

They don't. That's why you have to satisfy some virtuals manually at
install time.

As has already been explained, this is an unintended side effect which is
being fixed, it shouldn't affect the stage 3 tarballs.
