Bug#341524: yaird: fails to upgrade from linux-2.4 to 2.6

[The Anarcat <anarcat@anarcat.ath.cx>]

Package: yaird
Version: 0.0.11-12
Severity: important


Hello,

I just upgraded to sid from sarge, and I'm having problems moving to the
kernel 2.6. First off, let me mention that the upgrade didn't go as
smoothly as planned, which was to be expected nowadays... My packages
for kernel-image-2.6 were removed somehow, probably due to the new
linux-image kernels. Anyways...

Now that I actually try to switch to 2.6, some weird problem doesn't
want to let me. I tried this:

# aptitude install yaird
[...]
# tail -1 /etc/kernel-img.conf
ramdisk = /usr/sbin/mkinitrd.yaird
# : note that I also tried without the above line
# aptitude install linux-image-k7
[...]
The following NEW packages will be installed:
  linux-image-2.6-k7 linux-image-2.6.14-2-k7 linux-image-k7 
[...]

You are attempting to install an initrd kernel image (version
2.6.14-2-k7) while running a kernel of version 2.4.27-2-k7, but
you have no suitable ramdisk generation tool installed among 
/usr/sbin/mkinitrd.yaird.  This will break the installation, unless a
suitable ramdisk generation tool is also being installed right
now.

Seems to me that yaird doesn't support migration from 2.4 to 2.6.14. It does support anything below 2.6.13 though:

# mkinitrd --supported-host-version=2.4.27-2-k7 --supported-target-version=2.6.12 && echo 1
1
# mkinitrd --supported-host-version=2.4.27-2-k7 --supported-target-version=2.6.13 && echo 1 
#

That is after adding the line to kernel-img.conf but i had the same result before.

Now, I *was* able to upgrade, using the initramfs-tools package. Maybe the dependency list for linux-image should be reversed for that package, ie. put initramfs before yaird.

# /usr/sbin/mkinitramfs  --supported-host-version=2.4.27-2-k7 --supported-target-version=2.6.14 && echo 1
1

I'm not sure I understand all the implications here, but I leave that all in your wise hands. I can help more if you tell me what to do. :)

Thanks,

a.
