SINGLE USER MODE

Morning,

Last night, we had decided to try an install patch kit 3 to help releave
some of our C2 woes. Much to our surprise, we could not get our Dec Alpha
1000 to boot in single user mode ( needed for the patch installation ).

So here is what we tried to date:

SRM console >>> set boot_osflags s ( to have the machine boot up in
single user mode ). Booted the machine and it hung at INIT: SINGLE USER
MODE, with the Dec Alpha just dead ( ie. no lights or activity ).

We called the Tech Support who had us try with the generic kernel and
still no go. We tried ussing "init s" and "init 0" but each time the
system would just hang at the same place.

We thought that C2 might be causing this problem and took a look ( based
of the sulogin man pages ) and found that both /etc/rc.config and
/etc/sia/matrix.conf had the appropriate SECURITY variable ( in this case
ENHANCED ). However we did not something pecular inwhihc we would like
any commentary: there is also a rc.conf file ( in /etc ) which I cannot
find any man page reference too. It has SECURITY = BASE. I would like to
know if this file has any use to the system.

A lil system info: we are running DU 4.0b and FIRMWARE 4.8 on the Alpha
box. All the onwership and permissions are properly set. "uerf -R "
reported no hardware problems and since it could not boot the syslogd
there are not no error logs to report.

Any help concerning rc.conf or SINGLE USER MODE system hang would be
appreciated. A summary will follow.

Thank you

side note: we even have Digital Tech baffled on this one. Presently they
are trying to recreat the same situation in their labs in hopes to find a
solution.
