Bits By The Pound

If a file named /fastboot exists, fsck will not be run on the next boot; useful when you’re going to give a presentation.

If a file named /forcefsck exists, the file system will be checked at the next boot, resetting the 30-mount count.

To create one of these files, you will need root permission: run

$ sudo touch /fastboot

or

$ sudo touch /forcefsck
