If /proc/cmdline is empty (like if root=... is set in /etc/cmdline),
modules.d/99base/init will crash with a message saying "can't shift that
many" right before switch_root. The problem is in the block of code that
tries to look for init args. It does something like:
read CMDLINE </proc/cpuinfo
[...]
set $CMDLINE
shift
If CMDLINE="" then "set $CMDLINE" will dump all the variables to stdout.
(That should be "set -- $CMDLINE" instead.) Since there's no $1, the
"shift" causes an error, and dracut crashes.
The 'shift' was copy-and-pasted from the previous block. It doesn't
belong here; remove it.
