Subject: initrdscripts: add $CMDLINE to init-live switch_root
X-Git-Tag: 2015-4~4001
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=5a2f4feeaac4f9278fa0cf808c2f495f0c19324f;p=openembedded-core.git

initrdscripts: add $CMDLINE to init-live switch_root

init-live.sh: $CMDLINE variable should be provided to switch_root
to let user specify runlevel on grub command line.
Feeding with -c /dev/console as well as busybox switch_root enables that option.
