We're trying to work out a clean way of managing that sort of
persistent stat

I've been thinking about this same thing, and I thought that relatively
static fallback list of environments plus an (persistant) index to tell
you what you've tried so far might work. I was considering stealing a
byte from the RTC CMOS to hold the state between reboots.

Hmmm... This does rely on the 'stuffed-kernel' eventually cleanly rebooting
the machine,

Sure. The problem is just implementing any persistence at all.
Consider that we support the following backing-stores for the kernel:
- UFS on local disk
- (V)FAT(32)
- NFS
- T
That particular feature could also be done with "once-persistence"
as in: On next reboot load this file...

It would be kind of cool if when managing a remote system if /kernel
failed to boot, then on the next boot, the loader will fire up
/kernel.old, or a /kernel.somethingorother.
Sort of a kernel-clean flag. Then 300 miles away, I can try stuff, and
have at least some assurance that I'll eventuall
