Out of some infinite wisdom something on my system decided to add fstab entry for "new" device after switching from IDE to PATA:
# Entry for /dev/LABEL=/ : LABEL=/ / reiserfs relatime,tail 1 1 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 none /tmp tmpfs defaults 0 0 # Entry for /dev/LABEL=swap : LABEL=swap swap swap defaults 0 0 # Entry for /dev/sda2 : UUID=72973377-c299-4ca6-ae94-2022b7dca58f /media/hd reiserfs defaults 0 0
Note that both / and /media/hd refer to the same device:
{pts/0}% sudo blkid /dev/sda1: TYPE="swap" LABEL="swap" UUID="3b4dc82c-a6e6-4609-be9e-16d9206ab7fd" /dev/sda2: UUID="72973377-c299-4ca6-ae94-2022b7dca58f" LABEL="/" TYPE="reiserfs"
And according to /proc/mounts both are mounted at the same time:
{pts/0}% cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / reiserfs rw 0 0 /dev /dev tmpfs rw 0 0 /proc /proc proc rw 0 0 /sys /sys sysfs rw 0 0 /proc/bus/usb /proc/bus/usb usbfs rw,devgid=43,devmode=664 0 0 none /dev/pts devpts rw,mode=620 0 0 none /dev/shm tmpfs rw 0 0 none /tmp tmpfs rw 0 0 none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0 /dev/sda2 /media/hd reiserfs rw 0 0 {pts/0}% ll /dev/root brw------- 1 root root 8, 2 2008-11-04 12:01 /dev/root {pts/0}% ll /dev/sda2 brw-rw---- 1 root disk 8, 2 2008-11-04 12:01 /dev/sda2
