Subject: initrdscripts/init-install*: Add rootwait when installing to USB devices
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=7f26cee3d8e4b2e9240b30c21be9fa7661186ccd;p=openembedded-core.git

initrdscripts/init-install*: Add rootwait when installing to USB devices

It can take a bit for USB devices to be detected, so if a USB device is
your rootfs and you don't set rootwait you will most likely get a kernel
panic. Fix this by adding rootwait to the kernel command line on
installation.

Fixes [YOCTO #9462].
