The <command>lastlog</command> 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 an 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).
