It simply performs automatic check of all filesystems. If there
are no serious errors, it continues to boot up.

For making it able to boot up even if some filesystem errors
were found, you may wish to change your init scripts to run
e2fsck with -y and without -a or -p options in order to fix
those errors automatically.

If it's production server - just bring it up ASAP: even if some
data appears to be lost, you have a backup (don't you?). For
experimental or other non-critical servers you may wish to run
`e2fsck -vy ${device}` for all your filesystems, check for stale
PID or lock files, etc.
