[gentoo-user] Exercising a bit of caution with prune

[gentoo-user] Exercising a bit of caution with prune

[Dale]

Hi,

On occasion I get a bit of cruft on my system.  So I do the emerge -Pp
world to see what can be removed.  I wanted some opinions on this list:

I know to be careful with some things, gcc, autoconf and such but what
in this list can NOT be removed?  Some of them I'm not sure about but I
don't want to break things either.  Explain your thinking/reasons if you
can.  May help me later on.

Thanks

Dale

--prune removed slotted packages, which are usually slotted for a reason.
This not only applies to autocont, db etc. but also to things like the
GNOME/GTK library packages in your list.

If you want to find packages that are no longer needed, you should be
using "emerge --depclean -p".

I don't have gnome installed on here but I think something else uses
it.  Maybe it doesn't need it anymore.  I also use java but I think I
use the one from Sun that has the fetch restriction thing on it.  Just
to see if my thinking is right, should I do a equery depends <name of
each thing in the list> to make sure nothing needs it before I remove
it?  This doesn't pick up all the different versions of kernels.  I
still need to check the prune one I guess.  For that at least.

Gosh, 885 installed.  Holy molly.  That's a lot.

Thanks

It is possible you installed something with a lot of gnome dependencies,
then removed it.

That would take a while for 30 packages. I'd remove a few at a time, the
least harmful looking first, and unmerge them. Then run "emerge -utvDN
world" to see if something wants to bring them back in. If not, remove
some more. Or you could quickpkg them all and unmerge the lot in one go

kernels are slotted, so you'd need prune to remove the older ones. If
you prefer to keep more than one installed, use "equery list -d
sources" to see which you have.

That depends on what you use your system for. I have 930 on my laptop but
only 246 on my server.

I have buildpkg in make.conf.  Isn't that the same thing?

Not exactly, but more than close enough for this. I use buildpkg too, it
can save a lot of time and some heartache if a dodgy glibc is released.

I don't know what your problem is, but I'll bet it's hard to pronounce.

I usually get a screwed up portage or mess up python.  It helps to have
them laying around even though it fills up my portage partition.
