Hi Tobias,

 I do not think that adding that dependency will increase the boot
time in general case but just changing the order of the operations.
However, in those hardware which the devices recognition is slow, then
the boot will slow down but probably are also those cases in which
the resize will fail. In fast hardware, I think that udevd is just
started before that script otherwise udevadm would have failed and the
script as well due to set -e. This because the systemd paralyse the
activities. At the moment, I am trying these changes on a virtual
machine and it is enough fast that the script with udevadm settle do
not fail nor slow down the boot in a noticeable way.

 I sent the patch v2 with this dependency. Also here in attachment.

 Thanks, R-
