I'm talking exactly about booting from an encrypted usb volume. This

early. In such case there is missing following step:
0. sleep $cryptsourcedelay
If i got it right, your statement is untrue. rootdelay is implemented in
/usr/share/initramfs-tools/scripts/init-premount/udev, which is executed
before any cryptsetup action is done in
/usr/share/initramfs-tools/scripts/local-top/cryptroot. According to the
initramfs-tools manpage, init-premount scripts are executed before
local-top, so sleep $rootdelay (2) is invoked before cryptsetup luksOpen
(1).
If rootdelay doesn't work for you, you might raise the value. If you
still object, then please proof that I'm wrong.
I agree...the initramfs-tools check for rootdelay should see that the
root device doesn't exist and wait (since root will be set to something
like /dev/mapper/blablabla)...so the sleep should already be there
unless I'm mistaken.
