The impermanence module asserts that the persistent-storage volume and
every volume it bind-mounts into are available in early boot. Persisted
user dirs land under /home, so both /persist and the @home subvolume
must have neededForBoot = true. disko and nixos-generate-config leave it
at the default (false), so a fresh install with impermanence enabled
aborted with:
All filesystems used for persistent storage must have the option
"neededForBoot" set to true.
Please fix the following filesystems: /persist /home
Declare neededForBoot in the module that imposes the requirement.
