Mine has all those, plus SeIncreaseQuotaPrivilege (possibly thanks to 
the above from Marco).

It seems that I managed to de-configure sshd somehow. There's no 
sshd_config in /etc/ (just the skeleton in /etc/defaults/), and 
sshd-host-config doesn't seem to exist, either. So, I blew away the sshd 
and cygrunsrv services and their associated users and re-ran 
ssh-host-config. All is well now... except that now an enormous ascii 
art hippo greets me at login. Ick.

Thanks,
Ryan
