It is the result of a discussion we had on IRC. I tried to make the properties interface as generic and extensible as possible. Comments are welcome. Currently the command looks like this: btrfs fi prop /path/to/object [name[=value]] Some people may prefer other forms. For example I got suggestions for these forms: btrfs set/get /path/to/object [name [value]] btrfs prop /pach/to/object [name[=value]] (and also without the =) I'm open to more suggestions and a discussion on this. I'm definitely for removing the fi[lesystem] prefix but I'm neutral to the other suggestions made so far. For now, I've implemented three properties: 1. read-only. Usable on subvolumes to toggle the read-only flags. 2. label. I looked through btrfs to find good examples of things that could be moved to the new properties interface and the filesystem label looked like a good one. There are for sure more, but that is something for later (and maybe for someone else). I would suggest to move everthing that makes sense over to the props interface and mark the old interfaces as deprecated. Comments on this are welcome. Alex.
