It works fine with ubuntu too :)
Some lines from /etc/init.d/checkfs.sh:

Code:
--------------------
    #
  # Check the rest of the file systems.
  #
  if [ ! -f /fastboot ] && [ -z "$ac" ]
  then
  if [ -f /forcefsck ]
  then
  force="-f"
  else
  force=""
  fi
  
--------------------

...


Code:
--------------------
    sudo touch /forcefsck
--------------------
 will force check at boottime while 
Code:
--------------------
    sudo touch /fastboot
--------------------
 will bypass check

Also, tune2fs -i interval[d|m|w] allows you to set the interval between
each check:

Code:
--------------------
    tune2fs -i 1w
--------------------
 for a weekly check:cool:
