mkinitramfs blows up on casper dependency

[Jay Carlson]

When running uck-remaster to rebuild the xubuntu livecd, mkinitramfs blows up because 48xubuntu_maybe_ubiquity can't source /scripts/casper-functions. But this is the only script which fails.

I believe these scripts are designed to run outside the initrd environment when called with the "prereq" parameter.

The attached patch moves ". /scripts/casper-functions" below the prereq argument handling like the other scripts.

Bug found in binary package xubuntu-live-settings_12.04.11 from source package xubuntu-default-settings_12.04.11. The bug seems likely to be present in intermediate releases and HEAD.

For clarity, this is the error message that appears during execution of update-initramfs:

/tmp/mkinitramfs_TubQhv/scripts/casper-bottom/48xubuntu_maybe_ubiquity: 6: .: Can't open /scripts/casper-functions

However insignificant, the error message appearing is disconcerting when it's during an important process like building of the initramfs.

Status changed to 'Confirmed' because the bug affects multiple users.

I haven't looked at this in a bit, but I am pretty certain the result I experienced was more than just a diagnostic message at the time of filing. This blew up uck-remaster.

uck-remaster is a hack and I don't expect it to be supported. However, the ordering in 48xubuntu_maybe_ubiquity (compared to all similar parts) seemed to break an (unwritten?) architectural rule about casper-bottom parts. 48xu looked like it might cause problems for other packages later; I felt I should at least write down what I found. :-)

First of all, I'm not familiar with the actual problem. However, we need someone to check if this bug also affects the current LTS release of Ubuntu (14.04). If yes, does the proposed patch fix the bug without breaking anything else?

I am running XUbuntu 14.04 on a Sony VGN-NR11S laptop. I just got the following message when updating :

VGN-NR11S:~$ sudo dpkg-reconfigure initramfs-tools
