[Bug 2046570] Re: /usr/share/initramfs-tools/hooks/plymouth failed with return 1 due to warning in ldd output

[Duncan Joly]

I just made the fix but it still doesn't work. The issue seems to be
that the script tries to execute the command '4972' which of course is
not found. I've attached the stderr output of 'sudo update-initramfs -u'
in '127.txt'.
