[gentoo-catalyst] Missing /usr/src in installcd-stage3-minimal

[gentoo-catalyst] Missing /usr/src in installcd-stage3-minimal

[Zachary Bedell]

Greetings all,

I'm just beginning to play with Catalyst to create custom installcd images.  I've started with the Gentoo releng spec files from svn://anonsvn.gentoo.org/releng/trunk/releases/weekly/specs/amd64.  I managed to get through stage1-3 and installcd-stage1 without any trouble.  

Running installcd-stage2-minimal dies when trying to run Genkernel with "ln: failed to create symbolic link `/usr/src/linux': No such file or directory".  I hacked the kmerge.sh script to drop to a shell right after that happened and found that there was no /usr/src directory in the chroot.  Doing a `mkdir -p /usr/src` right before the ln call, and everything seems to work out after that.

I'm assuming something probably went wrong in an earlier stage, but I don't know enough about Catalyst yet to know quite where to look.

I can post spec files if they'd help, but I'm using stock from SVN with just some version number's changed around.  Does anyone have a guess where I might look, or is there any chance this might be a bug in the kmerge.sh script?  I'm using catalyst-2.0.6.916 at this point, but I may just give the -9999 build a try to see if that fixed the issue.

Any pointers would be appreciated.

Best regards,
Zac Bedell

The latest stage3 also does not add udev to the sysinit runlevel.
Lost about an hour to that.

Not neccessarily, think about who should create /usr/src. IMO it's
not at all really neccessary, it's just by (deprecated) convention
that there are kernel sources there.

It has little to do with catalyst itself. In any case, if you make
sure that your livecd-stage1 includes kernel sources, then I think
you'll sidestep around the problem.

Afaik the code in 9999 differs by more than just bugfixes.  Let me quote
from the -9999 ebuild:

  "The git master branch (what you get with this -9999 ebuild) for
   catalyst now contains the work-in-progress code for catalyst-3.x.
   Be aware that it's very likely that it will not be in a working
   state at any given point."

Also, please be aware that I have brought up the question of deleting
the 3.x altogether.  That means: In case you start using -9999 we really
need to know, so we don't pull the chair that you just sat down on.


On the /usr/src issue I would like to ask you to file a bug for it.
Copy-pasting from your original mail should be fine.  Thanks for
bringing it up.

Best,



Sebastian

Now that you mention it: I ran into the same problem.  It was ~20
something hours wasted over here I guess before I found that Xorg didn't
find my graphics card because of udev not being started.

Best,

Based on that, I think I'll stay away from the -9999's then.  I was able to get 2.0.6.916 working with either of two work arounds, so heading off to git land for this is a bit more fun than I'm allowed to have...

Opened:

https://bugs.gentoo.org/show_bug.cgi?id=374297

Just for laughs (I've been told I have an odd sense of humor...), I went back and ran installcd-stage1 with gentoo-sources included (cleaned everything up from installcd-stage[12] first of course), and removed the mkdir I added in kmerge.sh.  Worked fine as long as source was in installcd-stage1, so I've amended my bug report to reflect that.  Also included the one-liner patch to make it work without source in installcd-stage1.


One more minor thing I ran into:  

/usr/lib64/catalyst/targets/support/create-iso.sh: line 233: mkdosfs: command not found
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

`emerge sys-fs/dosfstools` of course fixed that right up.  Is that something I should open against Catalyst itself in "Gentoo Hosted Projects," or does that go to "Gentoo Linux" for the ebuild?


I've got a nice little ISO file built now.  Time to throw a VM at it and see how much of a mess I've made of things...


Thanks also for the pointer about udev.  Anything that saves me a wild goose chase is always appreciated.

Best regards,
Zac Bedell

What stage did you try?

Stage4.  Same for Peter.

Seen that one before as <https://bugs.gentoo.org/show_bug.cgi?id=274972>.

For anything new "Gentoo Hosted Projects"::"Catalyst" is perfect.

stage3-amd64-20110625.tar.bz2 or 20110630. I did the setup on 6/30
and grabbed the latest stage3 from a Swedish mirror. Can I check in
the installed system exactly which one was used?
