[PATCH 1/4] Modify instmods to not rely on the existence of modules.* files

[Victor Lowther]

This patch series aims to make dracut more distro-independent.  It includes
some of the functionality that Seewer Philippe posted to the list to make 
dracut work on Ubuntu.

depmod does not create these files on all distros (Debian, specifically),
so modify instmods to use pathname components and find to do what we want.

As a bonus, this removes the special-case for =ata.

[PATCH 2/4] Get rid of some RedHat specific modules and udev rules

[Victor Lowther]

They are not needed to boot with dracut, so away they go.

Also rewrite inst_rules to automatically search likely rule locations when
installing udev rules.

[PATCH 3/4] Steal rules we need from the latest udev package.

[Victor Lowther]

This should arguably be done by importing the udev git repo as a submodule,
but I am too lazy to figure out how to do that right now.

I suppose this could also be done by rewriting the 95udev-rules.sh module
for each distribution, but that is something best left to the distro 
maintainers once we acheive some sort of widespread adoption.  Until then,
stealing rules from upstream udev seems like the most portable solution.

[PATCH 4/4] Fix several inst functions.

[Victor Lowther]

Move file existence checking into the individual inst functions. This makes
things a bit easier to understand and maintain.

Without loading keymaps, if you have an encrypted root device, you may
not be able to (correctly) type your passphrase.

Stealing rules, though, means that they're almost certain to be out of
date as soon as they're present.  The right fix here is for distros not
to go off and think that they know better than upstream on how to write
udev rules.  But I'll let Kay chime in if he really wants to here ;-)

Re: [PATCH 3/4] Steal rules we need from the latest udev package.

[Thiago Galesi]

I'm not sure how udev works, but do we really need ALL the rules??
Like v4l, printer, floppy!! etc

If we're going to import rules and keep it built-in, I would take only
the bare minimal

We probably don't, but I really do not want to get into the business of
maintaining our own dracut-specific set of rules.  These are stolen
directly from the udev git tree without any editing whatsoever.  The
goal would be to import the udev got tree as a submodule of the dracut
udev tree and copy them with cp every time dracut was rebuilt, but I am
too lazy to learn how to do that right now.

In terms of files, I think this is pretty close to it. I am happy to be
proven wrong, however. :)

In terms of lines, there is certainly some fat to be trimmed, but I
don't think we should be in the business of hand-crafting rules beyond
the minimum needed to support cryptoroot, lvm, and networking.

Yep.  This is intended to be a quick and dirty hack for those of us who
prefer not to delve into the nuances of how each distro does things.  

Out of date does not mean as much to the initramfs, IMAO -- as long as
we can find and mount root, it does not matter how out of date the rules
are.

Exactly. And they will break horribly next month, when we e.g. switch
from vol_id to blkid.

Don't do that. There is no need to know how "distros" work, you only
need to know about Debian. :)

Oh, no. That will never work. The main udev rules cannot be
disconnected from the udev daemon and the udev tools in /lib/udev/,
they are tight together and have strong dependencies in the shipped
tools and the tool calling options. That's why the tools are in an
"application private directory" and not in /sbin. You will end up with
several versions of the rules in the dracut repo, and need to select
them based on the installed udev version. The current default udev
rules will not even work correctly on the "ancient" udev package
Debian ships today.

All other distros work together and ship a set of rules which is the
result of a merge of all the distro stuff. They all ship an identical
setup today. There is only one left, which thinks it can do better,
and I would not like to see broken workarounds for everybody in the
dracut repo. It should be a "Debian dracut module to work around their
weird idea of upstream", and not a "pain to maintain default" for all
other users. :)

> Mmmm... sweet scent of politics.  I get the feeling that many kilobytes

Yeah, it seems hard for some kids to share their toys. :) But it's
pretty much over, there is not much to discuss anymore. We all ship
the same stuff, and share the same bugs. If you want "Debian" use
Ubuntu. It's part of the upstream development, ships recent versions
which other stuff can develop against, and can depend on. :)

Kay

Ah,  I was not aware of that little tidbit of information.

inst_rules (in this patch series, at least) will try to grab rules from
the host system before using the ones I stole from udev upstream.  That
did not work on Debian due to their having a
different-enough-to-be-infuriating naming scheme, and I did not feel
like spending enough time examining their scheme to figure out the
"right" rules to grab.

Fair enough. Consider this patch withdrawn.

Good to know, but I think I will stick with Fedora for now.  It seems
like we have enough patches floating around on the mailing list right
now to have a good chance at making everything but Debian work without
too many distro-specific workarounds (or, at least we will once
switch_root is rewritten in C and packaged into util-linux)

Sounds fine. After the next sync, and if we can resolve the libexec
thing, I'll make it work on SUSE.

Does the tool already exist somewhere so that it can be merged? Is it
the busybox one?
Did someone send something Karel already?

I remember seeing something in dracut mentioning pages: "The code for
the replacement of this currently lives at
http://pjones.fedorapeople.org/mkstart/usr/lib/mkstart/switchroot.c "

I'm not sure this could be used, but it would be good to have
something merged to hack already ;)

Here are the results of a quick try, without digging into it:

These files are a Fedora invention, and the problem should be resolved
differently:
  cat: /lib/modules/2.6.27.10-2-default/modules.block: No such file or directory
  cat: /lib/modules/2.6.27.10-2-default/modules.block: No such file or directory
  cat: /lib/modules/2.6.27.10-2-default/modules.drm: No such file or directory

This does not exist, it's in /usr/share/terminfo/ here. Maybe it
should be fixed here?
  find: `/lib/terminfo': No such file or directory

This does not exist here, seems Fedora specific, and dracut hangs in
an endless loop:
  Installing /lib/udev/console_*
  cp: cannot stat `/lib/udev/console_*': No such file or directory
  Installing /lib/udev/console_*
  cp: cannot stat `/lib/udev/console_*': No such file or directory
  ./dracut-functions: line 107: /lib/udev/console_*: No such file or directory
  ...

This needs a "-p":
  mkdir /usr/libexec/dracut/rules.d
  mkdir: cannot create directory `/usr/libexec/dracut/rules.d': File exists

The first patch in this series should take care of that.

Should we even bother with terminfo if we are not including debugging  
stuff? Will cryptsetup work without it?

This one, or the one in Harald's dracut repo, or the one from busybox,
or the one from klibc, they should work fine. I guess the binary
should live in the dracut repo, and should be installed in
/usr/lib/dracut/*, as it is not useful for anything else, I expect. Or
is there any possible other user?

I took this switchroot.c, replaced my switch_root.c with it and fixed it, so 
that it works for me.

run-init.c from klibc sees realworld usage:
git clone git://git.kernel.org/pub/scm/libs/klibc/klibc.git
cd klibc/usr/kinit/run-init/
