[Bug 1571592] [NEW] Xenial server install fails with "targeted" initrd

[Tom Hager]

Public bug reported:

Hi,

I've been testing the Xenial Beta2 server ISO in our VMware environment and stumbled across
an issue with the "targeted" initrd option. I tested normal and minimal setup, with generic
and virtual kernels, but whenever I choose to use a targeted initrd, Xenial install fails when
configuring the kernel. 

I tested again with the latest daily build (17.4.) today, and the issue
is still there.

In the logs I found the following:

Apr 18 09:26:21 in-target: Examining /etc/kernel/postinst.d.^M
Apr 18 09:26:21 in-target: run-parts: executing /etc/kernel/postinst.d/apt-auto-removal 4.4.0-18-generic /boot/vmlinuz-4.4.0-18-generic^M

So here I am reporting the issue, with the requested output:

mount:

/dev/sda1 /target ext4 rw,relatime,errors=remount-ro,data=ordered 0 0
/dev/sr0 /target/media/cdrom iso9660 ro,relatime 0 0

I'll keep the VM at it's current state, so I can always gather more
information.

Cheers,
Tom.
