[Linaro-validation] Forced reboots are harmful

Hi

Experimenting with the dispatcher made me realize that forced reboots (on timeouts, for example) are an excellent way to damage the master image. At the very best we are forced to re-check the master image. At the very worst we may damage the superblock and generally hose the master.

Do you think it is feasible to mount the master read-only and only do r/w work on the test partitions?
