Two years or so ago I found the script below, allowing you to start any number of instances of acme. E.g. if you name the script acme9 you use acme9 -n 1, acme9 -n 2, etc., each of which can followed by the usual arguments you wish to pass on to acme.
Thanks to whomever wrote this. Mark. #!/bin/sh [ "$1" = -n ] && { export NAMESPACE=/tmp/ns.$USER.$2; mkdir -p "$NAMESPACE"; shift; shift; } 9p ls plumb/ >/dev/null 2>/dev/null || (cd /; 9 plumber) exec acme "$@"
