This allows for the disko scripts to be ran in more foreign environments
where we can't assume the basic utilities coreutils provides are
available or aren't 1-for-1 compatible (e.g. busybox utilities).
I.e. instead of effectively ignoring `discardPolicy` when combined with
`randomEncryption`, or adding a second option requiring the user to
repeat themselves (DRY violation), just enable both when requested via
`discardPolicy`.
Without this `discardPolicy` is a NOP when `randomEncryption` is
enabled.
This hopefully fixes the large memory consumption we have seen in the
past. Also presumably coreutils cp is more tuned for performance than
whatever nix does.
closure-info has one flaw, it's possible that this file contains stale
information when build are not reproducible and the local checksum
doesn't match what the remote build created.
The work-around here is that we disregard the hashes and re-compute with
what nar's we actually have locally instead.
The destroy script already has a bash interpreter in use, but when the
`disk-deactivate` script is ran, it calls out to /usr/bin/env to query
for a bash interpreter. When running the destroyScript in unique places
(such as the stage-1 initrd), /usr/bin/env might not exist, so we can
make destroyScript more self-contained by reusing the same bash.
The option `disko.devices.lvm_vg.<name>.lvs.<name>.priority` depends on
a different option that's unset by default breaking the manual build
like this:

This is especially noticeable when using `documentation.nixos.includeAllModules` locally.
Fixed the issue itself by adding a `defaultText` and added the
`disko-doc` job to the `checks` output so that CI hopefully catches this
from now on.
On 4Kn disks, 2048-sector alignment is equivalent to 8 MiB which is
excessive. Moreover, there is no point in specifying _any_ alignment
at all because sgdisk defaults to 1 MiB already.
Fixes#497.
The vmTools in nixpkgs shuts the VM down with poweroff -f, which does
not cleanly umount the filesystems. This may lead to filesystem
corruption on the newly created image.
