Simple questions about Ultrix

>>3) Can a DECstation (not VAXstation) 2000 with a 33MB disk run Ultrix?

Although it is not recommended, you can actually squeeze Ultrix 3.0 onto a
VS2000 with just a single RD32 (41MB).  It works a little better if you
first use chpt to increase the swap partition ("b") to, say,  10MB from
the default 7MB:

/dev/rrd0a
Current partition table:
partition     bottom        top       size    overlap
    a              0      15883      15884    c,f,h
    b          15884      36363      20480    c,d
    c              0      83203      83204    a,b,d,e,f,g,h
    d          31509      57371      25863    b,c,g
    e          57372      83203      25832    c,g
    f              0          0          0    a,c,h
    g          36364      83203      46840    c,d,e
    h              0          0          0    a,c,f

The RIS network boot software quite rightly refuses to recognize the
RD32 as a suitable system disk, so you have to drop out of the script
and do the mkfs stuff for the disk by hand, then copy in the software
you need.  I don't like to wait for the setld installation, so I copy
everything from a master host on the net that has the configuration I
want.  From the RIS miniroot I do "mount /dev/rd0a /mnt && cd /mnt &&
rsh masterhost sync ';' dump 0f - / | restore rf -" to get the root
file system, and do a similar rsh for the /usr file system.  I change
the name of the machine in /etc/rc.local, remove or truncate extraneous
log files and syserr files, touch up /etc/fstab if I need to, boot the
new machine and rebuild the sendmail.fc file.  I don't have room for
the X software (we run MIT X), so I get it over NFS from the masterhost.
