Postinst script invokes nonexistent /dev/MAKEDEV (was /sbin/MAKEDEV intended?)

[Daniel Richard G.]

Binary package hint: mdadm

This concerns mdadm 2.6.7.1-1ubuntu8 in Ubuntu Jaunty.

In the course of installing mdadm, I see

---->8----
Setting up mdadm (2.6.7.1-1ubuntu8) ...
Generating array device nodes... /var/lib/dpkg/info/mdadm.postinst: 170: /dev/MAKEDEV: not found
failed.
Generating mdadm.conf... done.
----8<----

# grep -n MAKEDEV /var/lib/dpkg/info/mdadm.postinst
27: if /dev/MAKEDEV md >&2 >/dev/null; then
# which MAKEDEV
/sbin/MAKEDEV

I believe this MAKEDEV program may have been relocated without the mdadm.postinst script being updated accordingly.

sudo ln -s /sbin/MAKEDEV /dev/MAKEDEV before installing mdadm seems to stop this bug.

This also affects Ubuntu 9.10 (x86_64).

It appears that this bug breaks the entire Linux Software RAID system, as none of the /dev/md* devices exist.

------

$ sudo ln -s /sbin/MAKEDEV /dev/MAKEDEV
$ sudo apt-get --no-install-recommends install mdadm
<<< SNIP --- installer doesn't complain about /dev/MAKEDEV >>>

$ sudo mdadm --add /dev/md0 /dev/sda3
mdadm: error opening /dev/md0: No such file or directory
stefanl@gondor:~$ ls -l /dev/md*
ls: cannot access /dev/md*: No such file or directory

------

Shouldn't the /dev/md* devices be created when the mdadm installer invokes /dev/MAKEDEV?
