Boot Cheat Codes
A commonly seen error is that you must choose from the menu displayed the config you want to boot with: pentoo changes=/dev/sdb1
changes=/dev/sdXY
Allow you to specify where to store configs, etc. In case you have a harddisk partition in FAT, ext2/3
or reiserfs
, you can specify it there so you should be asked if you want to store stuff on it.
