Sorry for the delay, I was on a short holiday in Bahrain :)

No problem - in feisty and edgy
directories I have all sources and patches against 1.0.4+svn26 version.

Feisty version:
 - Patched with the exact feisty patches I sent you earlier

Edgy version:
 - Patched with
   - the README note for encrypted LVM PV
   - with patch to wait for encrypted root device node
   - with patch to run cryptroot script before lvm scripts (this
     was another LVM crypto issue with edgy packages which hasn't been

So please, anyone interested in encrypted root filesystem fixes, please
test these package versions with either feisty or edgy. I myself tested
this with a encrypted LVM PV setup only, on both feisty and edgy.

Hmm, this variable does not affect cryptroot script - remember, this is
not really waiting for root device as I said above, this is waiting for
the  encrypted device, which may be LVM PV or directly encrypted root
device: in both cases you lose if the device is not available when the
cryptroot script is executed and the device just isn't there yet. We
just fail with rootdelay later, because the encryption could not be
opened earlier :=)

Maybe we should use rootdelay variable as well for maximum wait time for
encrypted root device node? Now it is not done.
