  Hmm, I was in a hurry. :-)  Even on Debian that's not quite right, it ought
to hide a larger range than it does (I think the real UIDs stop around 6000).
The other two are more work and have problems--for example, the 'dummy'
accounts on my system have their shell set to /bin/sh and several own their
home directories (www-data for example).  Is there any reliable, portable way
to find out which UIDs are real?  (perhaps see which accounts have a locked-out
password but that requires root privs, at least on a system with shadow
passwords; I believe gdmgreeter runs as gdm)
