[gentoo-portage-dev] Remove and upgrade in ebuild

[Andrea Carpani]

Hi everybody, I'm writing a custom ebuild and I'd like some actions to
be taken only when a package is removed from my system. 
At first I thought that pkg_postrm was the answer, but I discovered that
the function is also executed during an upgrade when the older version
is removed. 
I can't check has_version because at "pkg_postrm" time the package I'm
removing seems still registered. 

Any ideas? 
Thanks.

What about
if has_version \<$PF || has_version \>$PF; then
fi

btw. What kind of action would that be?

You could also just check whether a file that your package provides 
exists. Just remember to use the ROOT variable

I'll try this one. Thanks.

I need more control over "config" files: I've created a custom eclass
that saves to a custom /var/db/<dir>/<package> directory a list of
"protected" files belonging to a package at pkg_postinst time.

This list has to be removed if I remove the last instance of the
package.

Ciao.
