[gentoo-user] List installed packaged for 'system'

Hello,

short question:
How can I list all the installed packages with their
version no.s which belong to the virtual 'system' ?

   emerge -pe system  ---> this is giving me the list of
             packages  which are latest in the portage.
              I want the same list  but what is actually
              installed.

long story:

I had installed the 2006.1 release on an i686 system.
 Few weeks later I just synced the portage (only)
 using a snapshot. Now using quickpkg i want to
 create the binary packages of 'system' and
 install it on an underpowered system.

I got the following tip from this forum for that..

emerge -pe system|sed 's/\[ebuild  N    \] /=/g' > pkglist.out
cat pkglist.out | xargs quickpkg

But this fails because of the portage re-sync. Hence my question.


Also from the man page

       --emptytree (-e)
              Reinstalls  all world packages and their
              dependencies to the current USE specifi-
              cations while differing from the installed
              set of packages as little as possible.

What is the real meaning of the term empty tree here?
It is something more than including the dependencies ?


thanks
sathish

This fails with portage >= 2.1.1 (iirc). Before that --emptytree caused all 
packages to show up as New - i.e. as not installed. With portage >= 2.1.1 
they'll show as installed i.e. U(pdate) or R(eplace)... `man emerge` for 
details. And that's not the only thing that's flawed with that sed. It gets 
the version that would be installed rather that what is installed...

This should work:

# cd /var/db/pkg && \
    emerge -peq system | sed -n 's|^\[ebuild[^]]*\] \([^ $]\+\).*$|\1|p' | \
    sed -r 's/-[^-]+(-r[0-9]+)*$//' | while read pkg; do
        for p in "${pkg}-"*; do
            quickpkg "=$p";
        done;
    done

It's reinstall targets and all dependencies (indirect as well as direct). It 
used to be pretend nothing is installed but it doesn't really do that anymore 
(would result in stupid circular deps aborts even though the deps were 
installed)...

Probably a good idea to insert a `sort -u`:

    sed -r 's/-[^-]+(-r[0-9]+)*$//' | sort -u | while read pkg; do

Hah, I thought `quickpkg automake` would only make a binpkg for the highest 
version available. Turns out it handles all versions installed. So...

# emerge -peq system | sed -n 's|^\[ebuild[^]]*\] \([^ $]\+\).*$|\1|p' | \
    sed -r 's/-[^-]+(-r[0-9]+)*$//' | sort -u | xargs quickpkg

:)

Thanks, I was able to make the binary packages.
But my attempt to install 2006.1 on the low end machine was a disaster.
I will start a separate thread on that.
