I apologize I’m not looking at the gui at this second but I don’t believe they exist. Firstly, Luks 2 has some support in grub now, so should be accessible for /boot. Secondly I’d like to see these options
it might be a good idea to detect an SSD (probably the most common now) and auto add the last 2. Since discards can affect security an advanced checkbox with a warning in red would be a good idea.
Both are supported (and do the exact same thing), but as far as I know, only discard is mentioned in the documentation. So to safeguard against allow-discards being deprecated, “discard” might be the safer option to invoke.
(It’s happened in the past where multiple flags/options apply the same setting or command, yet as time goes on, some are dropped or deprecated in favor of the more “official” ones.)
Ironically, “allow-discards” is less ambiguous and more clearly implies what is being done.
