[gentoo-user] Slots

[Jeff Grossman]

I have just realized about programs that can be installed in slots.
Is there a way for me to find out what programs are installed in more
than one slot on my computer?  Can I tell if a particular program in a
slot is still needed?

Thanks,
Jeff

"emerge --prune --pretend world" will tell you all packages that have
more than one version installed (ie. slotted).

As for finding out whether a particular version of a slotted package
is still needed or not, well, you could do:

emerge --prune <pkg>
emerge -Dv world
revdep-rebuild

But the above is a bit dangerous, and could break your system.  Be careful.

Thanks for the information.  That is one are where I think Gentoo can
definitely improve.  Making it so you can tell if removing a package
will kill anything.  I would imagine this is probably not an easy task
though.

You can check whether the package you intend to remove is a dependency
of another package ;-) You can do it with "equery depends <package>".

Cheers,

I like the old 'etcat'.  You can still find it on your system at 
/usr/share/doc/gentoolkit-<version>/deprecated/etcat/etcat.

I use 'etcat versions <pkg>' all the time.  The number in parentheses is 
the slot that package is in.  E.G. for php:

[ Results for search key           : php ]
[ Candidate applications found : 13 ]

 Only printing found installed programs.

*  dev-lang/php :
        [ ~ ] 4.3.11-r4 (4)
        [ ~ ] 4.4.0-r4 (4)
        [  I] 4.4.1-r2 (4)
        [M~ ] 5.0.4-r4 (5)
        [M~ ] 5.0.5-r4 (5)
*  dev-php/php :
        [   ] 4.3.11 (0)
        [   ] 4.3.11-r1 (0)
        [   ] 4.3.11-r3 (0)
        [   ] 4.3.11-r4 (0)
        [   ] 4.4.0 (0)
        [   ] 4.4.0-r1 (0)
        [   ] 4.4.0-r3 (0)
        [   ] 4.4.0-r4 (0)

This shows that I have ver 4.4.1-r2 installed on my system in slot 4.

I haven't found an equivalent w/ equery.  I create a symbolic link from 
the etcat location above to /usr/local/bin.  However, everytime 
gentoolkit is updated, I have to update the link.

Cheers,
Kevin

maybe there should be some options when updating and emerge tries to bring 
in new slot, see, now i have qt3 and qt4, qt3 was emerged as kde dependence 
but nothing depends on qt4. so there waste of time and space unless i don't 
need qt4 for development or whatever. am i right?

Hey group,

I have dev-db/mysql 5.0.18-r30 installed.  After a sync I get the 
following when I run:

emerge -avb dev-db/mysql-5.0.19

Calculating dependencies ...done!
[ebuild  NS   ] dev-db/mysql-5.0.19  +berkdb -big-tables -cluster -debug 
-embedded -extraengine -max-idx-128 -minimal +perl (-selinux) -srvdir 
+ssl -static 19,074 kB

Total size of downloads: 19,074 kB

I read about slots, however I didn't see anywhere to do an upgrade 
instead of a slot.  I don't want/need to versions of mysql on my system. 
  Is there an option to emerge to tell it to only use the latest version 
of mysql?  Or do I need to emerge -c the older mysql?

Thanks!  I read searched Google for Gentoo slots and got everything
about slots except for what I wanted :)
