[gentoo-user] Portage wants to re-emerge old kernel sources

[gentoo-user] Portage wants to re-emerge old kernel sources

[Grant]

On one of my Gentoo systems, portage wants to re-emerge
hardened-sources-2.6.16-r10 and hardened-sources-2.6.14-r7 because of
(-doc%).  I'm currently using hardened-sources-2.6.18-hardened, but
whenever new kernel sources are emerged, I just manually rm -rf the
old sources in /usr/src.  I guess portage wants to re-emerge the old
sources because it thinks they are still installed.

How can I let portage know that those old sources aren't installed anymore?

By unmerging them ?

# emerge -Cva =hardened-sources-2.6.16-r10 =hardened-sources-2.6.14-r7

Yes, you can:

$ equery list --duplicates [<searchstring>]

In your case <searchstring> should be 'sources'. Without <searchstring>
it looks for all duplicates, installed in so-called slots.

'man equery' for more info. The tool is in the gentoolkit package.

It's also faster to rm -fr the directories before unmerging. You'd have
to do it afterwards anyway, to remove the files that portage did not
install (unless you run make mrproper) but doing it first speeds things
up a lot as it avoids portage deleting each file individually.

Heh. I unmerged 4 old kernels packages a few days ago. The deleting  
took 20 minutes (!) Not surprising when you consider there were >30,000 
files in each tree, and each one installed by portage has it's md5 sum 
checked, then deleted. rm -rf would've taken 20 seconds...

It is true then that emerge --depclean never unmerges slotted packages?

That's correct, but that's not what --depclean is for. emerge --prune
will remove all but thew highest slot - use with great care!

Just how would portage know that an old slot is no longer needed? Just because 
a newer version is installed doesn't mean it's been compiled or that the old 
is no longer needed (you might need to compile some package against the old 
that fails to compile against the new)...

For the more general case slot deps aren't allowed in the tree yet so it's not 
all that easy to figure out which slots are in use. You do risk breaking your 
system by pruning the wrong package..

Regardless, I do think app-portage/udept at least attempts to do this. I 
haven't tried it so I can't say how reliable it is, though.

Ok, yes, slot deps sounds like what I'm after here.  Is there a
portage command I can run to see which packages are installed in more
than one slot?  I'm having disk space problems on my laptop.

emerge -Pp

Though you should never run that without --pretend cause that will destroy 
your system.

I personally prefer 'equery list --duplicates' from my previous post. It
takes up little space. But I guess it's a taste thing, and you need the
gentoolkit package.

Just wanted to state an alternative :).

Ok, I guess this is where I either stop or find out if udept works.

# default emerge search
emerge -s hardened-sources

# this works great for cleaning out old versions like you want
emerge -Pp hardened-sources

# fast portage searchtool
emerge eix && update-eix && eix hardened-sources
