Thank you, I'm building a new kernel+world right now.  For some reason 
I thought we had already bumped those particular limits up past 16 
characters so I didn't look at them.  I ran into this problem because 
I'm using Samba's winbindd with nsswitch, and the usernames are 
prepended with our Windows 2000 domain name, making them longer than 
usual.  Samba, chown, ls, etc. don't seem to have a problem with these 
long names (nsswitch is great!), so they must not pay any attention to 
MAXLOGNAME and UT_NAMESIZE and that's what made me think it was 
specific to quotas.  Is there any reason this couldn't be bumped up to 
32 characters (or more) by default for better compatability with 
alternate namespaces?
