Problems installing gutsy with crypted partitions

[Josef Wolf]

Hello,

I noticed that 7.10 has the new d-i functionality to create encrypted
partitions at install time.  So I decided to give it a try.  I decided
to use the following setup:

 partition   size   mountpoint
 -----------------------------
      hda1   100MB  /boot   not crypted
      hda2    10GB  /       crypted, passphrase
      hda3     2GB  swap    crypted, random password
      hda4    10GB  /home   crypted, passprase

This setup worked as a charm with debian etch.

This is what I did:

1. In partman, I assigned hda2, hda3 and hda4 to "Use as a crypted volume".

2. I changed hda3 to use "random password".

3. Selected the new menu entry "assign crypted volumes" in partman's main
   menu.

4. Now, here's the first problem (this is inherited from debian): there's
   no way to skip the step to overwrite the crypted partitions with random
   data.  Ough!  I had to wait almost 1 hour to fill hda2, then I had to
   confirm that I really want to overwrite hda3.  Then I had to wait about
   15 more minutes, then confirm again for hda4, then wait one more hour.
   This results in sitting more than 2 hours and waiting for the random
   data procedure.

   What would one do with a 400gb disk?  Wait 40 hours?  There should
   _really_ be an option to skip the randomizing step.

5. I am asked to enter passphrase+confirmation for hda2.  I enter them

6. Then d-i says it is starting up the partitioner.
   Huh?  I would have expected to be asked for passphrase+confirmation
   for hda4!

7. d-i hangs at 47%

8. I switch to second console.  "ps ax" shows that
   /lib/partman/init.d/35dump hangs.

   Indeed, "tail /var/lib/partman" confirms that /lib/partman/35dump hangs


Any ideas why I am not asked for hda4 passphrase and what at causes
this hang?
