Fixes#130
This should fix pretty much all cases where spaces or other special
characters would break disko due to improper quoting. I searched for all
instances of '.label', '.device' and '.name', so I believe I caught
whatever I could.
In some cases I changed single quotes to double quotes for consistency.
I know we don't usually fix bugs in the legacy table type, but it was so
easy I couldn't resist.
This is not an issue when initially creating the partition because
device mapper will just map on top of the filesystem, but it breaks
incremental updates because the check for `TYPE=` will fail, and the
subsequent attempt to run `mkswap` also fails:
mkswap: cannot open /dev/disk/by-partlabel/disk-nix-store-swap: Device or resource busy
Instead, just don't do anything, NixOS will take care of it.
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.
