Probably known around here --

On F11 builds, the enumerated device for the SD cards (internal,
external) can and does change. More precisely:

 - Boot with only internal SD card present, and later insert an ext SD
card -- result: mmcblk0 is the internal SD card, and mmcblk1 the

 - Boot from the internal SD card, with an external SD card present --
result: swapped enumeration - mmcblk1 is the internal SD card, and
mmcblk0 the external.

So for example if you want /home on an external SD card, use UUIDs .

Drop down to init 1 and use this (dangerous) script
