[Bug 1525699] Re: Error message "/sbin/plymouthd: not found" is shown on booting

[Jani Uusitalo]

Those scripts are ran from the initrd, so it's looking for plymouth and
plymouthd in the initrd /bin and /sbin directories, and those are
probably missing the said files just as the error message says.

/usr/share/initramfs-tools/hooks/plymouth is responsible for copying the
plymouth executables onto the initrd, so to see why it fails to copy the
files, I added `set -x` to it and then ran `update-initramfs -v -u`.

In my case (I'm running Kodibuntu, I recently upgraded the underlying
system from 14.04 to 16.04) the issue was that the hook failed to find
Kodibuntu theme files for Plymouth, because it was looking for them in
/usr/share/plymouth/themes (which apparently is the standard place),
whereas the files actually resided in /lib/plymouth/themes for some
(legacy?) reason. The hook therefore determined that I have no working
Plymouth theme and thus don't need the executables.

After moving the theme files to /usr/share/plymouth/themes (and some
manual labor updating references in the files themselves as well as
Plymouth's alternatives) the hook now correctly finds those files and
then proceeds to copy the Plymouth executables onto the initrd.
