a/mkinitrd-1.4.7-x86_64-7.txz
Added support for the parameter names that control the delay before
attempting to mount the root filesystem, and the root file system type:
'rootdelay' 'rootfstype' respectively. These are the official/documented
parameters in the kernel documentation. The original parameters ('rootfs'
and 'waitforroot') may still be used.
Thanks to Thorsten Mühlfelder and Richard Lapointe for the suggestion.
For ARM devices: unless specified when the initrd is built, or at boot
time as a kernel parameter, wait a minimum of four seconds for the root
device to become ready.
Thanks to Jerome Pinot for the suggestion and the patch.
