Comment 0 for bug 1846762

OEM factory installation typically puts the Ubuntu media onto a recovery partition and uses a preseeding recipe to install into the remaining free space on the disk.

This casper change appears to have broken that behavior:

casper (1.415) eoan; urgency=medium

  * Persist logs on the install media by default:
    - Try to auto create a casper-rw filesystem on the install media if there
      appears to be at least 100MiB free on it.
    - Use a casper-rw filesystem for /var/log if it is not being used for
      persistence.
  * Fix some '|| continue's that got missed when check_dev got refactored into
    a function.

In my testing (in QEMU) I can errors that no free space can be found. Examining the disk I see that a casper-rw partition has been created in the free space taking up the entire disk.

Would you please consider to recognize the "nopersistent" kernel command line option already supported by casper to disable this behavior?
