Is there a way to allow single user login without interacting with ISL ?

Thanx for your replies

As referenced from shutdown(1M)

If neither -r (reboot) nor -h (halt) is specified, standalone and server systems are placed in single-user state. Either -r (reboot) or -h (halt) must be specified for a client; shutdown to single-user state is not allowed for a client.

# shutdown -y 0

# shutdown 0
will bring you into single user mode. However, if you are attempting to do any type of maintenance on /usr or /var where they need to be unmounted (ex. - extending either one) this won't work because they remain mounted. In that case you need to lgin from the ISL prompt.

I agree 'shutdown 0' will put you in single user.

Now maybe I'm mistaken (it wouldn't be the first time..). But I have also, at this point, extended /var on systems. I simply did a umount of /var and then extended it. Remounted it and to date I haven't had any problems with the systems.

Run "init s" from command prompt to bring system in single user mode.

Hi,

If you want to boot single user every time
without interacting with ISL, simply edit
the initdefault entry in /etc/inittab

Change 3 into 1 and you're ready.

Next time you reboot, your system will boot
in init mode 1 (single user)
