[Sunhelp] failed write of utmpx entry:" "

[Dennis L. Lund]

The problem is  that "init" trys to record its run-level change to /var after it has been
unmounted.

We do the following to correct this error:

# umount /var 
# mkdir /var/adm 
# ln -s /dev/null /var/adm/utmpx 
# ln -s /dev/null /var/adm/utmp 
# mount /var 

This will allow "init" to record its run-level change even after the /var filesystem gets 
unmounted during shutdown. The data itself is useless and the write will be discarded.

It works.
