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.
