When I halt/reboot my system I get "INIT: failed write of utmpx entry"

When the system shuts down, init(1m) updates /var/adm/utmp* to
reflect that fact.

If you have a separate /var filesystem, this operation will happen
after /var is unmounted and init complains:

INIT: failed write of utmpx entry:"s6"


INIT: failed write of utmpx entry:"rb"

You can safely ignore these messages.
