Years ago bash used to leave zombies around. Maybe reaping could be
added to rc.

p9p/9base rc doesn't do job control that I know of. Are you using
Byron's rc, or do you mean if a user subsequently runs bash job control
won't work?

Not a bashism.

Not a bashism.

Out of bash, dash, and busybox ash only bash as the history command
itself, but I don't quite get why it's wanted. In 14 years of bash use
I've used the command maybe 3 or 4 times, and then it was to grep for
some complex command I should probably have typed into a text editor
first. I can understand wanting history for interactive shells but
busybox ash provides that, (I can't speak for dash,) it just doesn't
provide the history builtin. I also can't see the point of history in
the init system. ;)

May be a fair reason to go with bash. busybox ash lacks it, but if my
perspective is worth anything, that hasn't annoyed me to the point of
stopping what I'm doing when hacking on my PDA.

I think busybox ash supports this. I imagine any shell which supports
editing of its own command line would support the same in read.
