Sorry to the list, as always I failed to RTFM!
I completely missed the fact that the vmur.ko module comes with its own
command "vmur" to interface with the RDR, PUN, and PRT.
There is a man page for vmur and it is a very capable command.
It handles short records, text conversion, and queries.
All in all a very nice addition to Linux for System z ;-)
And not yet Xmas ;-)

Does that make sense to do?
2) What's the best way to echo/cat the critical files to the VM SPOOLed
console log after every successful boot?
New with SLES-10-SP2 is the VM Unit Record kernel driver vmur.ko.
Some basic documentation is in the new Device Driver and Command manual.
It can be used to directly interact with the RDR, PUN, PRT (default 00c,
00d, 00e).
Example
First ensure the vmur module is loaded either at boot or via command:
modprobe vmur

Of course you'll have all the issues of LRECL (see above for DD with
BS=80) and EBCDIC/ASCII (use iconv).
have fun ;-)
