I like the idea of changing the interval, but I don't (as
others have also said) like your idea of disabling it.

So this is what I just made for my laptop:

: #!/bin/sh
: PARTS="/dev/hda1 /dev/hda2 /dev/hda6"
: if /usr/bin/on_ac_power
: then
: else
: fi
: for PART in $PARTS
: do
: done

( this file also has hdparm control in it to make the drive
sleep more when on batteries, but that is not to the point,
so I omitted those refs )

The reason I like this approach is that it makes the fsck
happen when on AC but unlikely when on DC.  But it doesn't
disable the fsck entirely.

Anyone have a reason why it would be bad to run tune2fs this
way at every reboot?
