This is perhaps a tangent but I'm wondering if this syntax could be clarified
so 'exec' isn't used to mean 'jexec'? Would also simplify things if subsequent
j/exec's didn't require the use of '+=' instead of '='. Ideally both should be
deprecated in favor of a sysrc-compatible ':'.
Would also be nice if non-0 exit codes didn't abort the entire sequence (without
hacking in a subshell;exit 0) and if the man page mentioned some of this.
Regarding the man page, there's a URL under AUTHORS that doesn't lead where you
might expect... Makes a good case for a policy forbidding non-freebsd.org URLs
in man pages.
Just MO,
Roger Marquis
