I don't do remote admin so have no direct experience, but I've read of two issues you might be running into. 1) Apparently it is or has been default to build stage-3 and GRP packages with USE=acl. People who turn that flag off and do an emerge --depclean without doing an emerge --newuse first end up breaking their system, because all the ordinary utilities are built against access control list libraries and a depclean removes them, leaving non-functional binaries. That's why there's the BIG BIG WARNING about using depclean without doing an emerge --newuse (and preferrably a revdep-rebuild both before and after, just to be sure) first. Unfortunately, there are a LOT of people who can't seem to read warnings, even BIG BIG warnings, that end up with broken systems. 2) There was a recent authentication issue where LDAP based remote authentication and access was in use. Apparently, it was a problem of trying to authenticate a user in LDAP before the network was up to do so. This caused VERY SLOW boots, and altho I'm not aware of it causing your issue directly, it's possible it could be related. Part of the fix was to ensure all necessary boot accounts could be authenticated locally, not just over the network using LDAP -- IOW ensure there are entries in the local passwd and group files as appropriate, and that the UID/GID align with what is expected. More than that, you'll probably need to get help from someone with more direct experience. -- Duncan - List replies preferred. No HTML msgs.
