Before sysinstall is simply "made available" as an option, it first needs t=
o be taught how to handle a monolithic txz file because the structure of th=
e system has changed.

Also... sysinstall expects to boot into a RW filesystem, and I don't know y=
et whether the architecture has changed in this respect. If bsdinstall does=
n't boot into an MFS, then having the boot loader set vfs.root.mountfrom.op=
tions to "rw" is of little effect (for example, if you're booting directly =
into an ISO 9660 filesystem which can't be made writable -- unionfs aside).

So, whatever prompt the user is given to choose between sysinstall and bsdi=
nstall... said prompt best be pretty early in the game (if we're going to f=
ork to two different operating environments: MFS versus ISO 9660).
