My question was about the procedure for putting a host in single user mode
in preparation for applying patches
The following procedure works fine after booting into single user mode.
# /sbin/bcheckrc
# swapon -a
# update
The above is the approved procedure (in some official doco which I don't
have).
Also:
Mount -u / will also remount the root file system in read/write mode. Then
you can mount the rest of the file systems required.
The kludge I have used before, is just to do a shutdown to single user
mode, which leaves some processes running that probably should not be left
running, and leaves all the file systems mounted. This kludge did not work
for me initially as one of the bugs the patch kit fixes is a bug in who.
This bug means that who returns run-level 0 when the machine is in
run-level s. Regardless of the method you use, you will have to do an init
s when the system is in single-user mode and who returns "who 0 0 s" before
dupatch will install anything.
Also don't forget to apply the Tru Cluster patch (TCR150DX-003).
