[pca] Single-User revisited

[Fred Chagnon]

I know it's an age-old question. To patch in single-user, or not.
I'm concerned mostly about the patches that require a reconfigure reboot.
For example sparc kernel patches 120011-14 or 127127-11. Has anyone had any
problems applying these patches in multi-user mode on a running system?

I'm asking because I would like to implement the use of a pca proxy, but I
figure in order to download a patch from the proxy, I can't be running in
single-user mode -- and as much as possible I would like the process to be
streamlined such that applying kernel patches uses pca the same as any other
trivial patch.

Thanks for any insight.
