[Bug 320482] [NEW] dmraid must not call udevadm trigger --action=add

[Giuseppe Iuculano]

Public bug reported:

Binary package hint: dmraid

(Originally reported against dkms on ubuntu, LP #320200)
dmraid must not call udevadm trigger --action=add in postinst.
This will have utterly dire consequences for the installed machine.

Major bugs will be apparent corruption of mounted filesystems (e.g.
"/usr: data error") until a reboot.
And critical bugs include the entire /dev changing to root:root/660 on
upgrade.

Simple fix is to use --action=change.

Cheers,
Giuseppe.
