In any case, it's just a log of who has logged in and when. If you don't need
that history, delete the file as root. The machinery will create it as needed.
You might look into logrotate, which would help keep it to a reasonable size.
lastlog is a *sparse* file that only records the last login of each user
at a fixed offset in the file (indexed by uid). If you have a user with a
large uid, the file will appear huge, but ls -s will show the true size.
Log rotation will not help at all.
