[gentoo-user] emerge --depclean -p output looks weird

[Dale]

Hi,

I run --depclean on occasion just to clean out some old cruft.  I got 
this output a bit ago and it is well . . . confusing me.  Here it is:

root@smoker / # emerge -p --depclean

*** WARNING ***  Depclean may break link level dependencies.  Thus, it is

Calculating dependencies... done!

What looks weird you ask, why is it listing them that way?  They are 
separately listed and I don't recall ever seeing it listed that way 
before.  They are usually in one section.

Another odd thing is this:

root@smoker / # uname -r
2.6.23-gentoo-r8
root@smoker / # ls -al /usr/src/
total 3
drwxr-xr-x  4 root root  176 2008-04-04 16:58 .
drwxr-xr-x 17 root root  496 2008-01-23 09:31 ..
-rw-r--r--  1 root root    0 2006-08-03 09:23 .keep
lrwxrwxrwx  1 root root   32 2008-04-04 16:58 linux -> 
/usr/src/linux-2.6.23-gentoo-r8/
drwxr-xr-x 20 root root 1424 2008-04-04 17:21 linux-2.6.23-gentoo-r8
drwxr-xr-x 21 root root 1472 2008-04-03 22:32 linux-2.6.24-gentoo-r4
root@smoker / #

It wants to remove the currently running kernel as well.  Seems it used 
to leave that one in the past.  I may be wrong tho.

Thoughts?

That's a side effect from the fix for this bug:

http://bugs.gentoo.org/show_bug.cgi?id=201045

The code was never written to preserve unmerge order, but now that
it's been tweaked to do so, it displays a bit differently in cases
like this. It would be possible to make it look like it used to in
cases when the order doesn't matter, but since it's only
superficial, it's not a really a high priority.

That's this bug:

http://bugs.gentoo.org/show_bug.cgi?id=198200

With <portage-2.2_pre the only solution is to add the versions that
you want to keep to the world file, like this:

emerge --noreplace =gentoo-sources-2.6.23-r8

After you do that, depclean shouldn't want to remove that one.

Aaaaaaa, I see now.  I didn't know you could put a specific version in 
the world file.  That's cool.  It worked too.

Now I can get rid of the other kernels too.  The newer kernel didn't get 
along with my Nvidia card for some reason.  It worked just slow as leap 
year.  Went back to my old kernel. 

Thanks for the info.
