When not attaching to an existing network namespace, pasta always
spawns an interactive shell in a new namespace to attach to. Most
commands which can issue a shell in a modified environment can also
issue other commands as well (e.g. env, strace). We want to allow
pasta to do the same.
Because of the way the non-option argument to pasta is currently
overloaded, allowing this requires some other changes to the way we
parse the command line.
David Gibson (8):
conf: Make the argument to --pcap option mandatory
conf: Use "-D none" and "-S none" instead of missing empty option
arguments
Correct manpage for --userns
Remove --nsrun-dir option
Move ENOENT error message into conf_ns_opt()
More deterministic detection of whether argument is a PID, PATH or
NAME
Use explicit --netns option rather than multiplexing with PID
Allow pasta to take a command to execute
