[Bug 1195504] Re: Add a noswap option to avoid accessing drives - w/ PATCH
Hello again ~ubuntu-installer develoeprs! Ran into this issue again. We observed a hang on reboot after installation until we added a `/sbin/swapoff -a` to the ubiquity ubiquity/success_command seed file entry. The issue is likely occurring because our seed file uses partman- auto to repartition the entire disk, including the swap partition. It would be great to have the `noswap` option so that our disk can be repartitioned without concern for any active swap partition.

Hi casper developers, please consider implementing this patch. It is needed for an Ubuntu live environment with some disk drive recovery tools that can be run from a live environment to avoid having to check the for an active swap partition on the disk that is being tested.

** Description changed:
- I would like to propose the following patch that adds a noswap Kernel
+ I would like to propose the attached patch that adds a noswap Kernel
parameter that disables casper's automatic discovery and activation of
any present swap partitions. The purpose is to not have the drives and
drivers in use so that they can be accessed or unloaded without issue.
