[Xen-devel] [PATCH OSSTEST v4 06/13] Osstest/Debian: support adding a rootdelay property to bootargs

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

arndale appears to be quite slow (and asynchronous) at finding it's
scsi controller. rootdelay=3 seems to do the trick.

For the dom0 case this involved refactoring the existing provision of
the commandline to be less open-coded in the boot script here doc.
