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. Yes, that the theory I know about :) But looks like they are not in world list of stage3. I'm 99% sure I didn't merge hashalot attr (as dependencies too). 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 %description This program will read a passphrase from standard input and print a binary (not printable) hash to standard output. The output is suitable for use as an encryption key. pwdb is used as a password and user account configuration thingy. Looks pretty important :-) I think so. 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. So, if I use reiserfs w/o ext attrs (option in kernel), I don't need it probably. Correct? When you figure out which ones to keep, it's best to put them in your world file. Either edit /var/lib/portage/world and stick the name at the end, or run 'emerge -n package-name' Thanks. -- Alan McKinnon alan dot mckinnon at gmail dot com -- Sergey -- gentoo-user@lists.gentoo.org mailing list

Not so fast. Check to see if you do have the xattr flag enabled.

Alan, thanks again :) Last question. How can I update selected packages correctly? Before I used 'emerge -uDN package_name' command, but it adds package to the world class, which is IMHO is not fully correct. To update whole system, I must use 'emerge -uDN world', right?
