Err... since we're talking RAID1 using Linux's Software raid, partitions
can be mounted manually as if they were just an ordinary disk. A /boot
using RAID 1 can be mounted as a partition of an individual hard disk.
Example: you /dev/md0 mounted as /boot is actually /dev/hda5 and
/dev/hdc5. Well, you can mount /dev/hda5 or /dev/hdc5 if you want if you
want to access the file system. Only good for read only stuff. If you're
going to write to the FS, you might need to re-sync your partitions
either by using raid tools or you might want to use dd (is this safe for
RAID 1? anybody who tried this to re-sync RAID-1 pairs?)
