[gentoo-portage-dev] manual uninstall

[Lanza Fabrizio]

 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/

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

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

 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?

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.

 emerge package will reinstall it...

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.
