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 usually much smaller than the one shown
|
|
by "<command>ls -l</command>" (which can indicate a really big file if
|
|
you have in <filename>passwd</filename> users with a high UID). You can
|
|
display its real size with "<command>ls -s</command>".

Large gaps in UID numbers will cause the lastlog program to run
|
|
longer with no output to the screen (i.e. if in lastlog database there
|
|
is no entries for users with UID between 170 and 800 lastlog will appear
|
|
to hang as it processes entries with UIDs 171-799).
