The lastlog 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 "ls -l"
(which can indicate a really big file if you have in passwd users with
a high UID). You can display its real size with "ls -s".

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).
