Public bug reported:
It is very good that it is easy to create and use a casper-rw partition
to run Ubuntu persistent live in the versions 19.10 and Focal Fossa, and
that it is even created automatically, when there is unallocated drive
space behind the used part in a live drive.
But I think the system for doing that is 'too eager'. Maybe it is a
feature that is left from the development and debugging phase.
- It would be enough (best), if the casper-rw partition is created only
when it is needed, that is when the live system is booted with the boot
option 'persistent'.
- We (I am talking for users who like persistent live drives) can accept
that the casper-rw partition is created even when the drive is booted
live only (without the boot option 'persistent').
- But we think it is a bug, that the live-only system is also mounting
the casper-rw partition on the mount point /var/log and/or /var/crash
and keeps it busy so that it cannot be unmounted.
This way the drive is not really live-only, and it is not possible to
manage the drive space behind the system in an independent way. For
example, it is not possible to detach the drive by using the boot option
'toram', and it is not possible to repair the casper-rw partition when
running live in the same drive. It will be necessary to have two linux
systems to do such tasks.
