So, yeah, pwdb is not a dependency anymore and people can safely remove it. I agree. It seems that ebuilds do change quite frequently without a revision bump. I wrote a tiny script to see all changed ebuilds. I could'nt make it just one script, but had to make two: one for makeing the diff (ebuilddifff.sh), and one to search for the ebuilds and call the former script (findebuildiffs.sh). Just put them in the same directory, and run ./findebuildiffs.sh | less in case you are interested in what has changed. From what I can see, it seems most changes are quite trivial and indeed not worth a revision bump. But sometimes, I am not so sure... For instances, glibc-2.7-r1 is now using a different patchset (version 1.6 instead of 1.4).

This is usually for bugfixes. Simple compile fixes do not warrant a revision bump; this is because they do not affect the installed package for users who already managed to compile it. Small documentation fixes are also usually not grounds for a new revision.

This is mail server and has mostly no additional packages except exim, mysql, spamassassin and some other. This means that you never explicitly merged them, they are not in world and are no longer required by anything else. There are normally three reasons: - you merged something that needed these packages, then unmerged them later, leaving these dependencies orphaned - you merged something else that used them, and in a recent update they are now using something else that provides the same functionality - they were required by some USE flag you once had, and you have now changed your USE, so the deps are no longer required. You'll need to look at each package and figure out if YOU need them, as we can't tell you that. I might think that you don't need your wife under any circumstances, and you might strongly disagree :-) I once knew what hashalot does. I forgot. It's something to do with cryptography pwdb is used as a password and user account configuration thingy. Looks pretty important :-) attr provides extended attributes to ext2/3 and XFS file systems, used by selinux and posix capabilities. If you use these features, you already are aware of it. When you figure out which ones to keep, it's best to put them in your world file.
