[Bug 2100503] [NEW] Casper wrong unmount when "toram" option is used

[Enrico Saul]

Public bug reported:

Casper does not unmount the source of the iso-file correctly if booted
with "toram" kernel commandline option.

If the installer iso is booted from "harddisk", e.g.
"Recovery"-Partition this behavior prohibits deployment of a new clean
Partitiontable. This might lead to residues of malicious software on the
"harddisk".


1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

Bug was experienced on:
- Description:	Ubuntu 22.04.5 LTS
  Release:	22.04

- Description:	Ubuntu 24.04.2 LTS
  Release:	24.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
Every Version of Casper since at least 2010

3) What you expected to happen
Bugfix from 2010 is applied

or implement a second "toram" option like "toramunmounted" or "toramclean"

4) What happened instead
