Great, look really nice :)
but this is not all what i mean.
For example fs specific messages: EXT4-fs blabla, if you look to source
you'll see "EXT3 FS" "EXT II FS" (fat is worse), if you need to grep it
will be nightmare. It seems like ext4 is mostly up to date, ext2/3 need
some work. Are there any work on this?
