The problem is not wtmpdb, wtmpdb cannot break the boot process and is very
robust to handle missing dbus reliable. It's only a symptom of the real problem
somewhere else.

Two older MicroOS installations got stuck during boot process after applying
the snapshot with the dbus-broker switch, both UEFI, one with traditional
grub2, one with systemd-boot. One got just stuck without any visible reason,
one in the emergency shell (sulogin, not initrd). No errors (except on one
machine the dbus error from wtmpdb) were visible. Only thing I noticed:
processes depending on dbus got started before dbus. wtmpdb was clearly visible
because of the dbus error, the other I remember was systemd-logind. None had
dbus-broker installed before. In both cases a hard reset lead to a working
system again.

I installed a fresh Tumbleweed Server yesterday (UEFI, systemd-boot), which
also got stuck in the first tries to boot it, but due to the splash screen
there was no chance to get any message from the system. The machine did never
show any boot problems before.

Since many other machines with the same setup come up without any problem, this
looks like a race somewhere.
