about these points the latency introduced by udevadm settle is
irrelevant in most cases about 0.1 seconds and because I commented the
code that checks for the free space in the last partition (all
resizing tools do that more efficiently) - in general the execution
time will be smaller - faster. In those platforms in which the boot
time grows up - most probably are the same that would fail because
they boot from a small internal storage device and might use
unpartitioned devices for rootfs or RW. Likely the qemu test that I
presented here in which vmlinuz and initrd image are separated from
the unpartitioned volume. In such a case the mount cannot trigger the
kernel to map the device because rootfs and bootfs are on different
devices. This is also the reason because I denominated the patch
"generalisation" - not only for having added btrfs. That support was
been in place since September 30th.
