You sync during that 30 days it's masked, do an emerge --pretend --update world, and see that it's going to downgrade. You check and the package is still there, so it's obviously a package.mask thing. You check package.mask and sure enough, there's a note in there saying that it's being removed. You decide you want to keep it, and move the still intact ebuild to your overlay and add an appropriate entry to your package.unmask. As others have pointed out, even if it's not in the tree any more, it's in /var/db/pkg. Even if for some reason insanity strikes and you don't do an emerge --pretend before you do the real emerge --update, and it's gone out of both the tree and /var/db/pkg, if you are running FEATURES=buildpkg (a /great/ way to avoid remerging, and have customized binary backups available to reinstall if necessary), you can get it from there (the ebuild is tacked onto the end of the tarball, thus the warning about additional data after the end of the tarball if you open it using tar or whatever, I've rescued or compared install ebuilds to current tree ebuilds from there a couple times). Even if all local copies, including backups, are wiped, the ebuilds and related files are in the viewCVS attic, as long as the raw sources are still available somewhere. -- Duncan - List replies preferred.
