[gentoo-user] Questions on the number of packages listed by 'emerge --depclean'

[Vladimir G. Ivanovic]

When I run 'emerge --depclean' I get this at the end as output:

        Packages installed:   2305
        Packages in world:    1762
        Packages in system:   64
        Unique package names: 2283
        Required packages:    2322
        
     1. It seems I'm missing 17 (2322 - 2305 = 17) packages. How can
        find out the names of these packages?
     2. It seems that I have 479 (2305 - 1762 - 64 = 479) packages that
        are in neither world nor system.
             A. What are the names of these packages?
             B. How did they get onto my system?
     3. It seems that I have 22 (2305 - 2283 = 22) packages that are
        slotted. How can I check this?

Thanks.

I don't know about this one, someone else can answer this.

They are dependencies of packages in your world file (world includes
system). The only packages in world are those you specified on the
command line.  Example: "emerge pysol" would emerge pysol and it's
dependencies, like pysol-sound-server.  Only pysol will actually be in
the world file.

"emerge -p --emptytree world" may show you all the packages, but you'll
want to pipe it to a pager, cause it'll be a long list.

"emerge -p --prune world" will show you, but don't run it without the -p
option, you may very well need some of those.

Paul,

Thanks for your help. One more question...

Does 'emerge --update --deep' look for updates to packages like, using
your example, pysol-sound-server, i.e. packages not in my world file?

emerge --update would catch this particular example. It updates the
packages listed plus any dependencies in their ebuilds. Adding --deep
makes emerge also consider the dependencies of those dependencies and so
on right down the tree.

WOW! That is a *huge* number of packages in world!

They are in the depclean output.  If it shows up in depclean, it is
not in world or system, nor a dependancy of something in world or
system.

emerge -Devp system | awk -F'] ' '{ print $2 }' | awk '{ print $1 }' >

equery -i list | grep "/" | while read pkg; do
    pkg="${pkg%-[0-9]*}"

They are dependancies of something in world or system.  "equery depends <pkg>".

"emerge --prune --pretend world"

Do *NOT* run this command without the --pretend option.

AMEN.  BE VERY CAREFUL with that one.  It can bite you badly.
