d-i daily build fails when building initrd (PowerMac7,3)

[Shyamal Prasad <shyamalprasad@verizon.net>]

Hi folks,

I've been away from my computer for a few months, but decided to give
the latest d-i netinstall daily build a spin today (March 26).

Besides the obvious known problem (default mirror) I find that a
powerpc64 install on a PowerMac7,3 (Dual 2Ghz G5) fails when trying to
install the kernel. Here is the tail end from the syslog

Mar 26 19:22:08 base-installer: info: Found kernels 'linux-image-2.6.15-1-powerpc64,linux-image-2.6-powerpc64'
Mar 26 19:22:08 base-installer: info: arch_kernel candidates: linux-image-2.6-powerpc64

Mar 26 19:22:08 base-installer: info: Available initramfs generator(s): 'initramfs-tools'
Mar 26 19:22:08 base-installer: error: exiting on error base-installer/initramfs/no-generator
Mar 26 19:22:14 init: ^MStarting pid 1123, console /dev/vc/2: '/bin/sh'

Also, when looking at the target disk it is clear that yaird is simply
missing (which I'm assuming is the root cause...)

~$ ls /mnt/chroot/usr/sbin/y* /mnt/chroot/usr/sbin/mki*
ls: /mnt/chroot/usr/sbin/mki*: No such file or directory
/mnt/chroot/usr/sbin/yabootconfig  /mnt/chroot/usr/sbin/ybin


I looked in the installation reports and the errata and did not see
this reported except for the cryptic errata saying  "[21 Mar 06] Base
installation will fail because of a script error." 

Since I've been away since December I thought I'd ask before filing a
new bug: is this new/unknown? Or is it just me? Should I file an
installation/bug report?

Thanks,
Shyamal
