[PATCH 01/31] Some dracut cleanups and bashification.

[Victor Lowther]

Hi, I enjoy hacking on system infrastructure and am a bash programming 
aficionado. With that in mind, I present this patch series against current
master -- it simplifies several bits of code and shaves about 200 lines out
of the codebase.  The final result has been tested on a Fedora 10 box that
uses lvm on top of dm-crypt, and it works fine.  I have not tested all
intermediate steps -- life is too short.

Comments, flames, commit access to the repo welcome.

These patches are also availble at http://git.fnordovax.org/dracut/ 

We have a path.  Do not specify full paths to commands that are in it.

[PATCH 02/31] Some dracut cleanups and bashification.

[Victor Lowther]

Add a simple getarg function.

If we ever need to get more than one kernel command line argument, this
function will pay for itself.  It relies on a feature of the way bash
handles string comparisons in [[ ]] statements -- the RHS is matched
according to globbing rules, and is not a straight string match.

[PATCH 23/31] Some dracut cleanups and bashification.

[Victor Lowther]

Rip out old recursive module loading, replace with something simpler

bash allows unlimited recursion and several other tricks to make
finding all the dependencies of a kernel module much simpler.

This nukes about 130 lines, most of it in dracut-functions.

This diff also touches some cleanups made in the inst function, and
tightens up findkeymap

[PATCH 30/31] Some dracut cleanups and bashification.

[Victor Lowther]

We no longer need plymouth. Since dracut is supposed to be distro agnostic,
probably best to not include it in the base backage, and work out an easy way
for distros to add it as needed.

init will ask for a passphrase directly if an encrypted root is detected.

Also, use udevadm settle with a 30 second timeout instead of a hardcoded
30 count loop.

The introduction of additional bashisms is something I'm not sold on.
Others have already expressed concern over what we have already,
so I think making it unnecessarily harder to switch to an alternative
shell may not be the best plan, especially when the benefits aren't
really that great.

Thanks for taking the time to get involved though, it's good to see
people actually playing with the code.

Well, it seems that most of the concern about bashisms has to do with  
the code that ends up on the initrd. Making that code strictly posix  
is probably a good thing.

There is no real benifit in having the initrd generating code be

INTERCAL.

Yeah, having the bits that end up in the initrd be posix is a good  
design constraint.

Good point.   I admit my comment was a knee-jerk reaction from reading
the first post without having read the whole patchset.

Well, this patchset does introduce bashisms in init. I have another  
that takes them out at the same time it adds three hook points. More  
details later.
