In the case of "installation from ULTRIX," we can expect the ULTRIX swap
space will be larger than 32MB-worth.  I checked ULTRIX /etc/disktab, and
learnt default partition of possible DECstations' 3.5" DEC drives are;

        RZ23, RZ24, RZ24L       33,345 KB
        RZ25, (RZ25L, RZ26)     65,536 KB

Unless former owner intensionally shrank swap space size, 32MB
diskimage is expected to work flawlessly (It seems safe even
considering 5" disks), however, it's a nice practice to check swap
space before writing after all. 

Installation with OS-less system or replaced disk will be totally
different story because there is no way to boot the machine up. 

And, it would be nice to provide concise information to inspect
the target hardwares using BOOT ROM monitor command, titled like
"before starting installation" section.
