Description

kernel cmdline: add dm_verity.dev_wait=1 dm_verity will wait for a device to be ready. This is needed in the factory installer so that dmsetup doesn't fail early before the usb device is visible. TEST=built images and booted them (x86-generic & factory installer) Prior to commit, need to ensure dev_wait doesn't break unverified boot behavior BUG=chromium-os:7451 Change-Id: I5b838b94e6a17dd0778331121311cdfe180991ce

Patch Set 1 #

Patch Set 2 : dev_wait blocks non-vboot; retesting images now #

Patch Set 3 : drop accidental inclusion! #

Patch Set 4 : fix use of non-existent flag #

tests passed, but I ended up tweaking it so that dev_wait is only =1 when rootfs
verification is enabled.  (Built with it enabled and disabled and
factory_install)

Now just investigating some switch_root weirdness prior to committing.

Cheers!
will
