[9fans] upas, cron and CPU servers

[Phillip Stanley-Marbell <narteh@ece.rutgers.edu>]

I successfully set up a CPU server, though I still need to tweak some
configs. Here are some notes and questions:

(1) When you first boot up a CPU server after recompiling the cpu server
kernel, and are prompted for hostdomain, DON'T just hit <return> !!!

(2) /sys/cron/upas -- owned by 'sys' in default config, should be owned by
upas ??

(3) /sys/log/cron is absent -- auth/cron tries to append to it and starts
gavoreeting bloody murder.

(4) start.xxx says to do

        for (i in '#m' '#i' '#S' '#t')
                bind -a $i /dev >/dev/null >[2]/dev/null

saying "... if you leave out '#m', rio will not start...", but rio won't
start anyway, since cpurc has no calls to aux/mouse and aux/vga. Right ?
Anyway, adding aux/mouse and aux/vga -l your.vga.size seems to do it.
