[pve-devel] [PATCH installer 1/2] clear zpool labels on selected disks' partitions

[Stoiko Ivanov]

along with `pvremove -ff` and writing zeroes to the first 16M of all
partitions, which belong to disks selected in the installer run `zpool
labelclear`.

This prevents a failure to boot after installation, if the disks were
previously also used as a zpool called rpool, but in a different configuration
(e.g. installing a raidzX first and then changing to raid10).
