From a relatively simple script, but I have yet to figure out the ideal arguments to pass to tar2sqfs. I've also experimented with bdebstrap a bit, though it has been even more difficult to enable zstd with yet another layer of abstraction... though there are definitely elements of it I like. >> The current default for tar2sqfs is xz, so passing --compressor xz is >> redundant. > > Maybe I should just drop the "--compressor xz" option and use the tar2sqfs > default and then you can post a bugreport about a good default with the > tar2sqfs people instead of here. ;) Good defaults may be context dependent... but if you really don't want to make it possible to pass custom arguments to tar2sqfs, I can't make you. :) Playing "good defaults" whack-a-mole with a handful of projects down the stack is not something I'm likely to pursue too much for fun. If it comes to that, I'll most likely just deal with the consequences of 'xz' or locally patch mmdebstrap. Thanks for considering, I know it's always a balancing act to avoid extra complication and still provide good defaults. live well, vagrant
