[pve-devel] [PATCH installer v2 1/2] fix #1603: create a new and unique machine-id

[Stoiko Ivanov]

see machine-id(5). The machine-id serves as a partial replacement to the hostid
(gethostid(3)) used by systemd and should be unique.

By generating a new one with `systemd-id128 new` (see machine-id(5),
sd-id128(3)) after the installation the newly installed system gets a unique
one.
