And I got permission! (Second attempt. If balsa eats this one, I'm
taking a hex editor to it.)

Hi Rob.
Can you please share with me your vision on what exactly toybox
initd should
look like?
Sorry for the delay, started a new job on monday and got behind on my
email. (I checked the webmail for the toybox archive, but you sent
this to my personal email. I've just now caught up to the 17th. :)
The thing is, for the last couple of months i'm doing embedded linux
on my
dayjob and our sysv scripts is not very fast, robust, concise,
flexible or
pretty much anything. After poking around i did not found init that
would be
small, well-written, maintained, and provide any significant
advantage over
busybox initd
Which made me thinking about writing my own, which is a bad idea
prob.
I would really like to know what are your plans for the toybox
initd, and/or
your thoughts on desing of pid1 in general for that matter.
Well, I did "oneit" already, which runs a single program. That way
you can launch a shell script as your init to bring the system up,
and designate one master program that will reboot the system if it
ever exits.
My next init will probably be something sysvinit-like, just because
so many people are used to it. I have a todo item to look at:
A) busybox init
B) android core init
C) klibc init
D) the old sysvinit man page
E) LSB 4.1 chapter 20, "System Initialization"
And see if I can come up with some common characteristics. I dunno if
this will wind up being an extension of oneit or a separate command.
Finally, I need to study upstart and systemd and see what that's all
about. But I haven't even started looking at that yet.
Ideally I'd like an init that could read an inittab, or the android
init data format, or the upstart/systemd formats, and behave
appropriately in each case without too much code duplication. But I
dunno yet how much actual code sharing that would involve and whether
or not it would be worth it. I haven't done the research or design
work yet.
Mind if I forward this response to the toybox mailing list?
Thanks,
Rob
