[gentoo-user] orphaned kernel sources?

[gentoo-user] orphaned kernel sources?

[Jarry]

So, with your help I finally checked all software installed on my
gentoo-server (thanks to everyone, who replied). There were a few
gentoo-sources (I think 5 or 6 different versions), so I used
"emerge --prune gentoo-sources" to leave only the last one.

Then I checked /usr/src, and I see there are still 2 subdirectories:
linux-2.6.12-gentoo-r6   (~50MB)
linux-2.6.13-gentoo-r5   (~300MB)

I'm surprised there is still 2.6.12-r6, because I unmerged it.
Can I delete it? Will this not break some dependencies?

Moreover, "emerge --pretend --prune" showed I have a few packages
with more than one version:

db (4.2.52_p2 , 1.85-r2)
automake (1.5, 1.6.3, 1.7.9-r1, 1.4_p6, 1.8.5-r3, 1.9.6-r1)
freetype (2.1.9-r1, 1.3.1.-r4)
autoconf (2.13, 2.59-r6)

Can I unmerge all but the last versions? Strange is, emerge does
not always want to leave the last version, for example it has
marked db 4.2.52 as "selected" for unmerge, and 1.85 as "protected"
(similar for freetype, 2.1.9 "selected", 1.3.1 "protected").
So can I leave "emerge --prune" to do its job without breaking
some dependencies? At least for automake and autoconf?

I think you can safely remove the orphaned folders, because anything that
needs the kernel source to compile, does so with the sources contained
within the folder that the /usr/src/linux symlink points to (make sure
it points to the kernel you're currently using).
Check out /lib/modules for orphaned folders as well.
To rebuild any packages that were compiled against an older kernel source, 
either use module-rebuild to update them (emerge module-rebuild)
, or run "emerge -va $(equery b /lib/modules | sed -e 's:^:>=:' )",
without the quotes.

Yes, you can delete linux-2.6.12-gentoo-r6.  This occurs because when 
you unmerge a package, it only removes the files that were part of that 
package, in this case, the kernel sources.  When you build the kernel, 
it creates a bunch of .o, .cmd, and .a files that are not removed by 
portage.  So yes, you can remove them without affecting anything.

My guess (based on the size) is that linux-2.6.13-gentoo-r5 is your 
current sources, so maybe you will want to keep that until your next 
kernel upgrade.

No.  Well, you can...but the next time you do an emerge -Dv world, they 
will get merged again.  Many packages depend upon specific versions of 
automake and autoconf.

In this case, the 'protected' version is whatever was most recently 
merged, not necessarily the highest version number.

Bear in mind, that if you've built kernels inside these folders then there
are object files, libraries and other debris from the build process that
portage knows nothing about - so unmerging doesn't remove the folder
completely.

The thing to do is to cd into each folder and do "make clean" to remove
files left over from the build process. Then run the emerge command to
remove the package.

yes  you can unmerge elderly kernel sources as you want to,  but it is faster 
to delete the directories first and than unmerginf

no!

you need several different db, automake and autoconf versions. Removing them 
will break your system in horrible ways! Do not touch them!
They are very much needed. Let them stay and do not disturb them.

Removing freetype will not break your system, but some apps may start to look 
extremly ugly ;)

  I checked, and find that I can't unmerge *ANY* of the sources,
including the current linux-2.6.13-gentoo-r3.  What's wrong with my
syntax???

thats because the package name is gentoo-sources-2.6.13-r3 not linux-2.6.13-gentoo-r3
