<para>
The <filename>lastlog</filename> file is a database which contains info
on the last login of each user. You should not rotate it. It is a sparse
file, so its size on the disk is much smaller than the one shown by
"<command>ls -l</command>" (which can indicate a really big file if
you have a high UID). You can display its real size with
"<command>ls -s</command>".

<para>
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, program will appear to hang as it processes UID 171-799).
