[gentoo-portage-dev] manual uninstall

 Hi,
I need to manually uninstall a package (without emerge --unmerge). How
do I tell emerge that a package is not installed (even if it is)? (I
basically need to force a reinstall, for a catalyst issue.)
 
 Another good question is: how does portage know that a package is
actually installed?
 
 Thank you.

you unmerge it ... if you insist on modifying the backend information, then 
see:

portage maintains installed package information in /var/db/pkg/
-mike

Er, manually meaning 'I want to delete anything it installed by hand'?
or 'I want to run the phases by hand'?

Why doesn't emerge -C work for this case?

emerge <package> will reinstall it...

Thanks, I will try this. If I delete the package info there, will
portage thing that the package is not installed, right?

I teorically want to manually delete what makes portage think that the
package is installed, so that it will install it again.
I cannot issue a direct emerge command because catalyst does not support
it. I don't have emerge available, though catalyst uses it internally.
But it's not customizable.

I need to achieve it without emerge.

Thanks.

If the stage supports it you can use N/fsscript. Or if you want to
unmerge the package at the beginning of the loop you could modify
/usr/lib/catalyst/targets/stageN/stageN-chroot.sh.
