Actually it is only when a filesystem is mounted read-write that you must
not run fsck on it.
Running it on a filesystem which is mounted read-only should be OK.
(Otherwise we would all be in a lot of trouble since when fsck is run
normally during the startup sequence the root filesystem (/) is mounted
read-only, and is in fact where the fsck binary is loaded from.)
