I can only speculate what's going on here, but there's a lot of
inconsistencies in UID<->username and GID<->group name mappings shown in
the Linux "id" program there.

On a native CentOS box, /usr/bin/id *does* return a username alongside
the uid number.  Example:

$ /usr/bin/id
uid=1535(jdc) gid=1535(jdc) groups=101(cvsusers),110(netops),{snipped}

So what I'm getting at: I don't know if the error from glib complaining
about getpwuid_r() "unknown user id" is actually saying "the UID 2139
is unknown", or if it's saying the passwd struct details aren't filled
in completely.  Taken from getpwuid_r(3) RETURN VALUES section:

   The functions getpwent_r(), getpwnam_r(), and getpwuid_r() return 0
   if no error occurred, or an error number to indicate failure.
   It is not an error if a matching entry is not found.  (Thus, if
   result is NULL and the return value is 0, no matching entry exists.)

Likewise I would expect the group names to be expanded as well -- it's
expanding some of them, but not all.  Why doesn't it know about GIDs
169, 259, 335, 356, 387, 402, 546, 584, and 605?

Does Linux emulation on FreeBSD require a separate passwd(5) file
compared to /etc/passwd?  I am not familiar with Linux emulation on
FreeBSD, which is why I find the above output weird.
