Bug Description

When system or user run command update-initramfs it prints errors:

update-initramfs: Generating /boot/initrd.img-3.19.0-28-generic
ln: nie udało się utworzyć dowiązania symbolicznego „/root/lib/systemd/system/cdrom.mount”: Nie ma takiego pliku ani katalogu
update-initramfs: Generating /boot/initrd.img-3.19.0-27-generic
ln: nie udało się utworzyć dowiązania symbolicznego „/root/lib/systemd/system/cdrom.mount”: Nie ma takiego pliku ani katalogu
update-initramfs: Generating /boot/initrd.img-3.19.0-26-generic
ln: nie udało się utworzyć dowiązania symbolicznego „/root/lib/systemd/system/cdrom.mount”: Nie ma takiego pliku ani katalogu

This means that there is no such file like /root/lib/systemd/system/cdrom.mount. After editing initramfs-tools/scripts/casper-bottom/25disable_cdrom.mount and correct path from:
/root/lib/systemd/system/cdrom.mount
to
/lib/systemd/system/cdrom.mount
generating initramfs stops printing errors.

Have you changed something else about initramfs-tools? Files in /usr/share/initramfs-tools/scripts/ are not normally run at update-initramfs time; they run in the context of the initramfs, and in that context, the path starting with /root is perfectly correct.

Can you please investigate and find out why that script is being run at all at update-initramfs time for you? It really shouldn't be.

Oh no, I see the problem - it's not the path, that script is lacking the usual prereqs handling. I'll fix.

No, I was change only /usr/share/initramfs-tools/scripts/casper-bottom/25disable_cdrom.mount file.

When fix will be available to download from repo?

I don't intend to upload it to vivid, because we aren't intending to do a point release of 15.04 and casper is mostly only useful if actually on the installation medium. It'll be in wily later today.

But that said, I have absolutely no idea whether downloading the wily casper package and installing it on a running 15.04 live session is a remotely sensible thing to do. Of course, running update-initramfs on a system with casper installed isn't normally a sensible thing to do either. If this isn't a live session, why do you have casper installed?

No, it's regular hard disk installation. I have checked why I have this package and it's required by systemback package.

OK, systemback isn't in Ubuntu. The error is cosmetic and you can just ignore it, or else get the maintainer of the PPA you're using to cherry-pick the patch.
