Description of problem:
 nfs-utils makes a nfsnobody user which on 64b platforms is 4294967294

 106  # Define the correct unsigned uid value for 32 or 64 bit archs
  107  %ifarch %{all_32bit_archs}
  108  %define nfsnobody_uid   65534
  109  %else
  110  %define nfsnobody_uid   4294967294
  111  %endif
  112
  113  # If UID 65534 (or 4294967294 64bit archs) is unassigned, create user "nfsnobody"
  114  cat /etc/passwd | cut -d':' -f 3 | grep --quiet %{nfsnobody_uid} 2>/dev/null
  115  if [ "$?" -eq 1 ]; then
  116          /usr/sbin/useradd -c "Anonymous NFS User" -r \
  117                  -s /sbin/nologin -u %{nfsnobody_uid} -d /var/lib/nfs nfsnobody 2>/dev/null || :
  118  fi

From the lastlog man page they have:

CAVEATS
      Large  gaps in uid numbers will cause the lastlog program to run longer
      with no output to the screen (i.e. if mmdf=800 and last  uid=170,  pro-
      gram will appear to hang as it processes uid 171-799).

Consequently when the nfs-utils package is installed /var/log/lastlog gets turned into a HUGE sparse file and lastlog takes a long time to run because of the huge gap.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install the nfs-utils package


  

Actual Results:  /var/log/lastlog is turned into a really large sparse file.  Lastlog takes a long time to run.  The customer discovered this when one of their backup like systems died when confronted with the 1.2TB lastlog file.

Expected Results:  The lastlog should not have been so large.  

Additional info:

This bugzilla is tied to IT #64891.  It has been discussed that nfs-utils needs to have an option in it to not add the nfsnobody user to the last database.  

Bugzilla ID 146214 mentions a new shadow-utils from CVS in which there is a new option "-l".  This option tells useradd not to add the user to the last database. 

nfs-utils somehow needs to use this option so it does not add the nfsnobody user to the last database.
