Oh no. This one will match all your /dev/sda1 etc too :) What yo want to do is either
grep -w /dev /proc/mount
or
awk '$2 == "/dev" { exit 0; } END { exit 1; }' /proc/mounts
or something similar. To distinguish between the following two cases:
/dev/sda1 / ext3 rw,noatime,data=ordered 0 0 devfs /dev tmpfs rw,nosuid,size=512k,mode=755 0 0
/mjt
