    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?
