which doesnt mean go ahead and use 'em. linux has a crappy password
system, FreeBSD is superior in this regard: can you imagine the sheer
INEFFICIENCY of doing UID lookups (for ls(1) for example) on a 10MB flat
file /etc/passwd?
FreeBSD at least uses Sleepycat DB hashes on /etc/passwd and
/etc/master.passwd -- but I dont know if it supports 32bit UIDs.
Certainly anyone trying to put more than maybe 20K users on 1 Linux box is
really asking for trouble. Intel just doesn't scale.
If you need those 80K users for some free email service or what-not (and
not general shell access) you might want to email me privately, I have a
very neat solution (well, that's my ego talking) that you might want to
consider. And it's Artistic too. :)
