If we did this the RIGHT way then we SHOULD use the partition
priority in the RDB record, after all, THAT'S WHAT IT'S THERE FOR!
i.e. have loadbsd or the bootsector loader scan the rdb for the
highest priority UNI\1, BSDR or whatever we end up calling it.

Well, as a fellow elderly fart who toiled and labored under AmigaUNIX
I'd like to clearify some things and point out the the AMIX boot
BS made the above necessary but with NetBSD we can do it THE RIGHT
AMIX was braindead in it's boot in that it used a seperate boot
partition from root in order to allow booting from s5 or ufs
filesystems, i.e. s5 doesn't have the 8k free area at the front of
the filesystem like ufs does for a bootstrap loader. If only UFS was
allowed then they could have put the bootstrap in the 8k on the
front of root and just use the RDB priority to decide who was
the root filesystem.
With NetBSD we can "DO THE RIGHT THING(tm)". We can put the direct
bootstrap stage 1 in the 8k area on the front of the root filesystem
and then use the rdb priority scheme + bootstrap smarts to
"do the right thing"!

True. It would be nice to have you along for the ride tho. But, I
suppose you'll keep the rest of us on our toes with new features
found only in MWBSD. B^).
I assume you'll still be lurking on the list to interject new ideas
and opinions yes?
I would like to take this opportunity to give a virtual brew and
pat on the back for all the work you've done for first the AmigaUNIX
community, libbsd and such, the AmigaDOS community, (gcc, ixemul.library
and such) and the NetBSD community (initial Amiga port and SUNOS
emulation) . You've given us all good platforms to start on our various
I'm sure we will be keeping a close watch out for your future capers.
Who knows, maybe when the 4.4 stuff is fully integrated, Amiga NetBSD
will tweek your interest once again!
