-# Serve Unix u9fs over SSH
-#
-# Basically, try each of the following until you find one that works:
-#
-#	srvssh unix
-#	srvssh -r unix
-#	srvssh -R unix
-#	srvssh -r -s unix
-#	srvssh -R -s unix
-#
-# and then never look back.  Note that "srvssh unix" should always
-# work.  It's just that if you're talking with certain sshd's, you'll get
-# hit by Nagle's algorithm and need to explore the other flags.
-
-# When using ssh to start u9fs, the only way to turn off
-# Nagle's algorithm (which kills the performance of RPC-based
-# protocols like 9P) is to allocate a pseudo-terminal.  The
-# command ssh -Rmp attempts to allocate a pseudo-terminal and
-# then put it in a transparent mode.  Especially when
-# connected to older SSH daemons, the connection ends up not
-# quite transparent.  To get around this, we explicity set the tty
-# mode on the command line as well.  The hope is that -Rmp makes
-# the connection transparent enough for the Tversion, and the stty
-# command will do the rest.  If -Rmp doesn't make the connection
-# transparent enough for the Tversion (but the stty commands do 
-# make the connection fully transparent) then add "-s 5" to the srv
-# command to tell it to wait 5 seconds before sending the Tversion.
-# That should be enough time for the stty to take effect.
