(In reply to mq from comment #4)

A suggestion: implement a boot configuration option to only initialize the root
device during boot, while other devices would be left to initialize in the
background. Later if a an operation is attempted on a device (such as mount),
if the device has not yet initialized, the operation would block until the
device is ready. This would considerably decrease boot times on all computers
which have optical drives that force read the media at initialization, or hard
disks (not hosting root, data storage) with slow spin-up.
