It's working on my terminal, using both password and rsa auth. I haven't tried genning up a CPU kernel with the new factotum yet.


I notice the new ssh doesn't seem to get along with srv -e.  I tried various permutations of -m, -r, -i, and -I, to no avail (trying to u9fs mount a FreeBSD machine).  It gets as far as starting u9fs, but the communication channel between srv and ssh isn't happy.  In particular, after running

  srv -e 'ssh foo u9fs -na none -u me' foo

the post message appears and the shell prompt comes up, but the underlying ssh still has the terminal window in raw mode. At this point you can type and run blind commands, but any attempts to mount /srv/foo will give you a mount that just generates cloning errors.  I'm guessing ssh might need a flag to force it to do its I/O on fds 0 and 1 rather than /dev/cons ... ?
