Well, this is a kind of deceptive word usage in "post-truth" times. In this case both "user" and "quota" are not valid... - by "user" I ment general word, not unix-user account; such user might possess some container running full-blown guest OS, - by "quota" btrfs means - I guess, dataset-quotas? In fact: https://btrfs.wiki.kernel.org/index.php/Quota_support "Quota support in BTRFS is implemented at a subvolume level by the use of quota groups or qgroup" - what the hell is "quota group" and how it differs from qgroup? According to btrfs-quota(8): "The quota groups (qgroups) are managed by the subcommand btrfs qgroup(8)" - they are the same... just completely different from traditional "quotas". My suggestion would be to completely remove the standalone "quota" word from btrfs documentation - there is no "quota", just "subvolume quota" or "qgroup" supported. -- Tomasz Pala <go...@pld-linux.org>
