In /sys/src/9/boot/local.c^connectlocal we have:
if(bind("#k", "/dev", MAFTER)<0)
I am booting locally off a fossil partition, so I'm pretty
sure this is the right code path. The bind seems to
work (I stuck a test right after that in my local local.c),
but by the time it gets around to starting venti, venti
can't see a file in /dev/fs. When booting finishes, the
file's in #k/fs, but #k isn't mounted anywhere.
Anyone know where/why this is getting lost? I'd like
to boot off a fs(3)-backed venti. I also tried telling
venti to get its arenas directly from #k/fs/arenas, but
that went poorly.

On the machines where it matters, mostly file servers, we have
bind -a '#k' /dev
in /cfg/$sysname/namespace. There's a newns() in init.c, at least.

Right, but how do you get your root file system if it's on a fs(3)
device? It looks like it should work, with connectlocalfossil
just a few lines after the bind in connectlocal, but that doesn't
seem to actually work for me. init.c (and thus /cfg/*) are much
later in the process.

did you write the config?

Hrm. This looks familiar, and I think I had a similar problem a long
time ago when I was trying to do the same. I think I had to modify
local.c. I can't check right now, but I will later this evening. If
you haven't found a solution, I'll let you know.
