Bug#299623: revisiting this bug

[martin f krafft]

I am sorry it took me so long to get back to this. I had a good read
over the code and this bug and I reached the conclusion that the
proposed fix is not 100% adequate.

The issue at stake is a postinst creation of /dev/md* devices by the
mdadm package. The original created the devices only when devfs was
not in use and /dev/md0 didn't exist already. The current solution
creates them if /dev/md0 does not exist.

This works, but it's a hack. Namely:

  - users of devfs will get an error (but who cares?)
  - udev is somewhat circumvented and MAKEDEV used instead. While
    this is ugly, it may also come with problems as udev gets more
    and more important.

Thus I propose to change it to use MAKEDEV only if /dev/md0 does not
already exist, devfs is not in use, and udev neither, like so:

  [ ! -e /dev/md0 ] && [ ! -e /dev/.devfsd ] && [ ! -e /dev/.udevdb ]

I am going to try this in 2.4.1-1, upgrading and clean installs,
with and without udev. If it works for udev, it should work for
devfs.

Stay tuned.
