I have investigated this some more. I will provide a solution for UCK
(Ubuntu Customization Kit) but it might apply to other contexts as well.
It is actually 3 distinct issues:
The main problem is the missing init scripts. This is a result from UCK
deactivating initctl (see also in the output of uck-chroot-rootfs:
"Deactivating initctl..."). This makes invoke-rc.d fail when trying to
run upstart jobs (Ubuntu uses upstart (not init) for the services in
question). The "/etc/init.d/* not found" is a followup error and
actually misleading.
The fix described previously (modifying .prerm/.postinst files) does
work, but it's better to fix it globally and not for each affected
package. I found it's best to do it right in invoke-rc.d. Just change
all "exit 100" to "exit 0" in /usr/sbin/invoke-rc.d (in the chroot!).
That will generally ignore missing init scripts. Don't forget to revert
the change afterwards.
The second problem is the missing /scripts directory ("Can't open
/scripts/casper-functions" error). This can be fixed with the following
command (in the chroot!):
ln -s /usr/share/initramfs-tools/scripts /scripts
The third problem is that the UCK applies a hack on the zz-update-grub
scripts which in my case creates an invalid syntax and thus breaks the
upgrade as well (dependency problems on the linux-image-generic
package). The fix is described in my comment #10.
In order to avoid applying these patches manually each time, I modified
UCK to apply it when entering chroot, and revert it when exiting
(amongst the other stuff that UCK does in these stages). It's all in
/usr/lib/uck/remaster-live-cd.sh.
I made a fork of the UCK source code on github and applied the changes.
You may just get the follwing file
https://raw.githubusercontent.com/jox/UCK/master/libraries/remaster-
live-cd.sh
and replace your /usr/lib/uck/remaster-live-cd.sh with it (this time
*not* in the chroot...).
You might also apply the attached patch as follows:
$ cd /usr/lib/uck
$ sudo patch -p2 remaster-live-cd.sh.bak < \
/path/to/fix-uck-missing-initd-scripts-1.patch
(The path in the patch is different since it is from the source code. Running
patch with -p2 from the directory the file is located will apply it properly.)
You may view the changes on github as well:
Fixed missing /scripts dir in chroot.

Title:
failure to update libpam-systemd in 14.04 due to missing logind init
script
Status in “systemd” package in Ubuntu:
Fix Released
Status in “systemd” source package in Trusty:
Triaged
Status in “systemd” source package in Utopic:

Bug description:
Hi,
while running inside an i386 lubuntu 14.04 chroot, upgrading libpam-
systemd to version 204-5ubuntu20.2 fails leaving dpkg in a broken
state. 'apt-get -f install' from within the chroot will not fix it,
but if the build is made bootable and put into a iso/VM you can
recover that way in a live session.
the problem seems to be the /var/lib/dpkg/info/libpam-systemd:i386.prerm
script failing to bring down the logind daemon with 'invoke-rc.d systemd-logind
stop', because invoke-rd.d is only looking for the /etc/init.d/ script (doesn't
exist) and not /etc/init/systemd-logind.conf (does exist).

In a web-search I notice a few others running into the same bug,
chatter on irc at [18:10], http://irclogs.ubuntu.com/2013/05/28
/%23ubuntu-devel.txt
someone else's build log:
https://launchpad.net/~qutim/+archive/qutim/+build/6039800
launchpad bug #1323575 seems to be a duplicate of this one.
perhaps related to older launchpad bug #1305395 ?
note we are also suffering from a failure with update-initramfs, not sure of
the root cause of that one but I thought I'd mention it in case they were
related, since they both started happening about the same time, a couple weeks
ago. (launchpad bug #1317602)
It all worked ok after the inital releases of 14.04, so something to do with
a package update since then.
thanks,
Hamish
