consider merging stuff from the debian packaging upstream
I think it should be considered (perhaps in cooperation with the Debian maintainers - I have no idea whether they'd like that idea or not), whether it makes sense to move parts of the Debian package upstream.
I'm specifically thinking about
- The whole crypttab concept/syntax/documentation.
- cryptdisks_start, cryptdisks_stop
- The concept of keyscripts, their "API", documentation, etc.
- Perhaps some of the keyscripts, as far as they're generally usable (i.e. not Debian specific).
- Maybe things like askpass (the passphrase query tool that can be used from keyscripts, and which could be extended to support stuff like plymouth, etc.)
Moving the initramfstools hooks/scripts upstream is probably not really helpful as this is rather debian specific.
I hope the Debian maintainers don't feel stepped on their toes when they read about this,... it's not my intention to "steal" their work away from them, but I actually think that they did such great work with the above, that cryptsetup in general (and other distros) should benefit from this as well. Especially all distros could benefit, because "standardisation" here and WRT to keyscript APIs, etc. could lead to keyscripts from / made for other distros could be more easily across distros as well.
 Especially with respect to crypttab/etc. I made some extension proposals/ideas at the Debian BTS, which may also be generally useful, respectively deserve cross-distro standardisation/harmonisation:
