Depends on the error, if you miss a 'then' on an if, yeah, you'll get
an error, but other things, it's not an error, just a different result
:) But I know what you mean.
Third party and config files is not bash specific. By nature,
/etc/network.d is root writable only, although making it root only
readable may be a good idea too to hide network keys.

Arrays is the only thing I can think of,
Or.......... my dream setup, ala bsd
home="connection wireless key 12346 interface ipw0"
main="connection multi childs home,work "
but it's very nasty to parse -- not impossible though, I have done it
in experiments -- and involves wrapping all of the iwconfig and
ifconfig options to acheive an equivalent functionality level.
wrapping that many is icky.

I hope they're nicely implemented, but i'm hardly one to judge my own
code :) It does have it's faults.

Further thoughts, and implementation idea:
I thought about an ini style config. That could work *really* well.
I don't want to drop the bash side of these either, it'll be too long
before we see something new, and these work well, I havn't picked up
any new bugs for a few days now... not to say they don't exist.
So... a Csomething based parser of ini files. Would be totally awesome.
Orr.... another file....
profiles=home something else
.... and you get the idea.
If I could run: netini main.connection and get the value from the ini
file, I'll rewrite these netscripts in a night and they will work far
better, and the codebase will be far better.
I *could* write such a thing in python pretty quickly but I can see
people not liking that. Which is fair enough.
If this config file form is agreeable... i could write an interim
python one and implement that until either I mess around with C or
someone else writes one... ini shouldn't be difficult given it's
ubiquity, so there' probably existing parsers. otherwise... any other
format suggestions are welcome.
