udev and yaird

udev and yaird

[Moshe Yudkowsky]

I'm trying to puzzle out a problem with udev and yaird. Please bear with 
me -- I suspect that this is a yaird problem, but I'm not entirely certain.

I'm using 2.6.14, Debian unstable. (2.6.14-2-k7)

Symptom: the ide-cd module does not load at boot time. No /dev entries 
are created.

Problem: when I use cpio to look at the boot image, I see that the init 
script loads ide-{core, generic, disk} and some other modules, but not 
ide-cd.

Question: doesn't the ide-cd load the way it used to in prior versions 
of the kernel created with mkinitrd?

I suspect that the problem is that yaird doesn't use the udev script 
under /usr/share/initramfs-tools/scripts, for example. That udev script 
would test each ide device and load ide-cd if it found a cdrom.

Even if I modify /etc/modules I still don't get ide-cd in yaird images. 
Instead, yaird just looks for the bare minimum to mount the root file 
system:

> yaird: goal: mountdir, / (/etc/yaird/Default.cfg:143)
> yaird: action: insmod, /lib/modules/2.6.14-2-k7/kernel/drivers/ide/ide-core.ko {optionList=-- }
> yaird: action: insmod, /lib/modules/2.6.14-2-k7/kernel/drivers/ide/ide-generic.ko {optionList=-- }
> yaird: action: insmod, /lib/modules/2.6.14-2-k7/kernel/drivers/ide/ide-disk.ko {optionList=-- }
> yaird: hardware: completed ide0/0.0
> yaird: action: mkbdev, /dev/hda {sysname=hda }
> yaird: action: mkbdev, /dev/hda1 {sysname=hda/hda1 }
> yaird: action: insmod, /lib/modules/2.6.14-2-k7/kernel/drivers/md/md-mod.ko {optionList=-- }
> yaird: action: insmod, /lib/modules/2.6.14-2-k7/kernel/drivers/md/raid1.ko {optionList=-- }
> yaird: action: mdadm, /dev/md1 {components=ARRAY(0x89b78c8) major=9 minor=1 uuidX42a331:676c7ce4:06417154:50dffb65 }
> yaird: action: insmod, /lib/modules/2.6.14-2-k7/kernel/fs/reiserfs/reiserfs.ko {optionList=-- }
> yaird: action: mount, /mnt {device=/dev/md1 fsType=reiserfs isRoot=1 options=-- }


So, why doesn't yaird -- or something else -- modprobe ide-cd anymore? 
Is this a distro problem, a yaird problem, or a  "udev needs to remind 
yaird to include something in /etc/yaird/Default.cfg" problem?

Thanks,
  Moshe
