This is a Centos-5 system. here's an excerpt from its man page:
SYNOPSIS
/sbin/shutdown [-t sec] [-arkhncfFHP] time [warning-message]
DESCRIPTION
<snip>
OPTIONS
<snip>
-f Skip fsck on reboot.
<snip>
The -f flag means \u2018reboot fast\u2019. This only creates an advisory file /fastboot which can be tested
by the system when it comes up again. The boot rc file can test if this file is present, and
decide not to run fsck(1) since the system has been shut down in the proper way. After that, the
boot process should remove /fastboot.
