Bug#1088279: cdimage.debian.org: Unable to assign 'mount point' in net-install for encrypted mapped devices

[Wiebe van der Worp <w@vanderworp.org>]

Package: cdimage.debian.org
Severity: grave
Tags: d-i
Justification: renders package unusable
X-Debbugs-Cc: w@vanderworp.org

Dear Maintainer,

   * What led up to the situation?
     Trying to install Debian 12
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     net-installer refuses to give the option to offer a "use as: ..." during installation.
   * What was the outcome of this action?
     Not able to install.
   * What outcome did you expect instead?
     Assigment of mount point.

Please take a look at https://forums.debian.net/viewtopic.php?t=161054 
As explained, the net-installer seems to have a bug not offering an option to set a mount point.
The code used in the DVD-installer works as expected.
Also missing are some valuable clues about the order of things:
  * Configure an encrypted device
  * Create the device
  * Modify its mount point

Hope all is clear, thanks and best regards, Wiebe
