@lumi @stilic everything i do as "root" has a 1 in 200 chance of irreparably fucking up my entire system and i'm completely sick of this fucking shit where everyone accepts that that's the most "power" or "control" you can ever have over a system: when the half-assed permissions system in the VFS layer doesn't return EPERM. are you listening to yourself? WE SHOULD BE BUILDING THE FUCKING FILESYSTEMS FROM SCRATCH WITH OUR BARE HANDS!!!!!
nobody has ever tried to design an OS around an algebraic (i.e. simple and extensible) semantics for how i/o modifies process-local and shared state, and it's why every single fucking build system is incredibly slow and does not help you one bit with avoiding someone introducing backdoors. both git and every other approach to checksumming a directory tree do the absolute most, in an intentional mathematical sense, to ensure the user of the system has absolutely no meaningful understanding of how the system's in-memory state is generated from its persistent state on disk, and vice versa.
haven't you noticed that literally every single self-appointed filesystem fuckboy is actively one of the worst people on the fucking planet??? that's because they crave fucking power and they know the filesystem is an incredibly simple way to legitimize constructions that are just immensely obviously intended to harm people!
