Hmmm, OK. I mis-read, assuming it was flash-specific. I can't promise
to do much testing for you just yet, though - really busy on other
stuff atm.

OK, cool.

We *try* to do the alpha builds every few months, but it's a (very!)
flexible schedule at this stage of the release process. It depends on
kibi and me having time to do things - he's the d-i release manager,
and I run the CD/DVD builds.
The hard deadline will be near the end of 2020, when we freeze
Bullseye for the full release. We'll then switch to doing release
candidates for d-i, and at that point we will only want to be taking
bugfixes.

To be honest, I'm genuinely not sure. I've never had to play with that
piece myself. Checking the code/changelog in partman-basicfilesystems,
I *think* it's a list of the mount options that are allowed for a
specific filesystem, so that d-i can validate what options the user
has chosen for a filesystem. But I'm not 100% sure, sorry!
