ext2 to ext3

[Joseph C. Lininger]

As far as adding the journal, no need to boot to single user mode before issuing the tune2fs command. However, you will need to remount the file system with the new type. Just to be safe, I'd would recommend totally restarting the machine since this will ensure this works properly. Changing the FS on the root filesystem generally only works properly after a restart.
