Hi,
Although this solves the immediate problem of all existing options
becoming no-ops, the new -j option still behaves strangely if it is not
used with "-j" and the jail name as the first two arguments, since the
shift commands will shift away other arguments.
One way to fix this avoids depending on the exact options known by the
jailed service(8) and accepts that the -j option must be first (either
-j JAIL as two arguments or -jJAIL as one argument). This parsing would
be open-coded and there would be only one getopts loop.
Another way to fix this allows using the -j option as any other option.
This would also use one getopts loop and reconstruct a command line for
the jailed service(8) based on the variables like ENABLED (the values
for set options can be changed to simplify this since the rest of the
script only cares about non-empty or not).
