QubesOS
Enable Trim by default (Or provide installation option) for SSD drives
Qubes OS version:
Q 4.0
Expected behavior:
Trim is enabled if the user is using SSD or at least installation option is presented
Actual behavior:
User must enable trim through a cumbersome manual process outlined here: https://www.qubes-os.org/doc/disk-trim/
General notes:
I think most users in 2018 expect that trim is enabled by default. Almost all users of Qubes utilize an SSD so this affects almost every user I imagine.
I have been running Qubes for quite some time assuming it trimmed. So, at a minimum a big warning during installation should be made that Trim will not be done on the SSD unless manual action is taken post-installation. Not trimming is against user expectations in the current year I think.
Trim is far more secure than not using trim. Without Trim the machine is far more vulnerable to forensics. As a result it should be enabled by default to prevent forensics.
Even more likely duplicate of #3686. Please have a look at the discussion there concerning the security considerations.
My head hurts after reading all of the linked discussions; how the heck does this even apply to a btrfs Qubes install?

You're the first to mention btrfs on this issue, so perhaps the first question is: How does btrfs apply here?
