Ah, thanks for that - I'll note it away for not-too-distant future reference.
The emulator structures at the moment look for the ELF interpreter and
try to switch on that, but I think that'll bite us with SysVR4 because
all the SysVR4 OSs will use the same ELF interpreter pathname, and because
it doesn't work as a discriminator anyway (Solaris executables still need
to be specifically branded, or you need to rely on kern.fallback_elf_brand).
Additional discriminators like this (even if they're bodgy crap ones)
are useful things to know about.
