The [users.root] override in redbear-full.toml only set shell, which
replaced (not merged) the base.toml entry that had uid=0 gid=0
password="password". Without explicit uid/gid, the installer assigned
root UID 1000, causing D-Bus to fail looking up user "root" and
"messagebus" — all D-Bus clients (sessiond, polkit, udisks, upower)
timed out and exited.
Verified: D-Bus daemon starts, polkit registers PolicyKit1, sessiond
registers login1, zero timeouts or retries in QEMU boot.
