[PATCH 00/10] SUSE S/390 integration

[PATCH 00/10] SUSE S/390 integration

[Hannes Reinecke]

Hi all,

SUSE is keeping the S/390 device configuration in udev rules,
on rule per device.
And it doesn't have the RH-specific configuration scripts (obviously).
This patchset abstracts away the RH-specific configuration and
adds modules to make dracut boot on SLES installations.

Please apply.

Hannes Reinecke (10):
  95dasd: Install kernel modules only once
  95dasd: Only install module if normalize_dasd_arg is present
  95dasd_mod: make dasd_cio_free optional
  95zfcp: Make installation optional
  95znet: Make installation optional
  Install /bin/mount
  Fixup keymap setting for openSUSE
  Check for plymouth lib directories
  Add DASD configuration for SuSE
  Add zfcp scripts for SUSE

[PATCH 01/10] 95dasd: Install kernel modules only once

[Hannes Reinecke]

Move kernel module selection to 95dasd_mod and make 95dasd depend
on that module.

Why so complicated and not use "inst_multiple -o" ??
Or, if you prefer inst_multiple_optional, replace all other occurences of
"inst_multiple -o" with inst_multiple_optional also.

After much debate and soul-searching it was found that

a) /bin/mount is _REQUIRED_ to be present
b) dracut will only copy /usr/bin/mount

So if /bin is _not_ a symlink to /usr/bin, but the individual
programs are, /bin/mount doesn't find it's way into the initrd.
Nor do several other programs.

How to approach this fundamentally?
I would prefer to have 'inst' checking for symlinks, and copy them
over if required.
Adding them manually seems ineffectual to me.
But I'll do whatever is desired here ...

Cheers,

Hannes

Like already discussed, we should alter dracut-install to search all PATH
elements, instead of just taking the first one.

http://git.kernel.org/cgit/boot/dracut/dracut.git/tree/install/dracut-install.c#n787

http://git.kernel.org/cgit/boot/dracut/dracut.git/tree/install/dracut-install.c#n851

http://git.kernel.org/cgit/boot/dracut/dracut.git/tree/install/dracut-install.c#n883

Will do, and also cleanup dracut-install.c in the process.
