[gentoo-user] Can I exclude a package from --depclean's consideration?

[gentoo-user] Can I exclude a package from --depclean's consideration?

[Paul Hartman]

"emerge --depclean" always wants to remove all but the most recent
version of gentoo-sources. I read the manpage and can't figure out how
to exclude this package. The manpage states:

"Packages that are part of the world set will always be kept."

However, if I have sys-kernel/gentoo-sources in world, it still wants
to remove all but the most recent version of that package, which I
think is the correct behavior... just not what I desire.

For now I am working around this by placing version-specific package
atoms into my world file, but I am just curious if there is a
different way of "masking" them from depclean -- one that does not
require me to manually edit my world file every time a new kernel
revision is installed.

So, my question: Is there a way to tell depclean to never remove *any*
version of gentoo-sources?

Thanks.

It's kinda case of "italian strike" - doing the job to the letter ;)

That's where portage-2.2 sets find another use.
Just add following set to /usr/share/portage/config/sets.conf:

  [kernels]
  class = portage.sets.dbapi.OwnerSet
  world-candidate = False
  files = /usr/src

And append "@kernels" line to /var/lib/portage/world_sets
Now any installed (even with -1) kernel should be safe from ravenous
depclean.

Hi,

did you read the first lines of this file ?

# WARNING: default set configuration, DO NOT CHANGE.
# If you want to change anything redefine the relevant section in
# /etc/portage/sets.conf. Any changes to this file will be lost on the next
# portage update, and configuration errors here might upset portage in
# unexpected ways.

Please make all the changes in /etc/portage/

regards,

Boris

If you read the man page (man emerge) you'll arrive at:

   emerge --noreplace =gentoo-sources-1.2.3-r4

Guess it's some kind of mind-habit of avoiding uppercase text in the
head of important configuration files, sorry.

That is what I'm already doing (recording version-specific atom in my
world file). I was trying to find a more generic way, that will
prevent me from the need to specify exact versions. Thanks :)

Perfect! It does exactly what I wanted. I created sets.conf in
/etc/portage/ as Boris pointed out.

Thank you very much for your help!

What would I add to /etc/portage/sets.conf to exclude gcc from depclean?
thanks

I'd add these to sets:

  [gcc-preserve]
  class = portage.sets.shell.CommandOutputSet
  command = /usr/local/sbin/gcc-list

This to /usr/local/sbin/gcc-list:

  #!/bin/sh
  for PKG in `ls -1 /var/db/pkg/sys-devel | grep -E '^gcc-[[:digit:].]+(-r.)?$'`
  do echo '=sys-devel/'${i}
  done

And '@gcc-preserve' to /var/lib/portage/world_sets


Alternatively, you can define set as files in /usr/libexec/gcc:

  [gcc-preserve]
  class = portage.sets.dbapi.OwnerSet
  world-candidate = False
  files = /usr/libexec/gcc

Looks simplier, but somewhat dirty and probably a bit slower.

Thanks Mike,
I was hoping it was as simple as the kernel-sources example. I got 
caught a few months back by dep cleaning gcc :( I did not want to 
rebuild everything with the latest gcc at that time but my hand was 
forced at that point.
