In contrast, NTFS exposes owners as UUIDs (much larger than a uid that any *NIX program understands) and has only ACLs (which are not expressed with the same verbs as NFSv4 or POSIX ACLs), so you need some translation layer and need to be careful that this doesn’t introduce incompatibilities with the Windows system. You may also have ACLs, but they’re optional. In a typical *NIX filesystem, you have an small integer UID combined with a two-byte bitmap of permissions.

I also don’t know how the NTFS driver handles file ownership and permissions. It’s fairly easy to define a key-value pair that means setuid, but if you’re dual booting and Windows is also using the filesystem then you may need to be careful to not accidentally lose that metadata. It’s fairly easy to support reading and writing key-value pairs from an NTFS filesystem but full support means understanding what all of the keys mean and what needs updating for each operation. This is also the big problem for anything claiming to ‘support NTFS’. This means that you can take a filesystem with encryption enabled and mount it with an old version of NT and it just won’t be able to read some things. Compression, encryption, and even simple things like directories, are built on top of the same low-level abstraction. Large values can (as with BeFS) be stored in disk blocks, small values are stored in a reserved region that looks a little bit like a FAT filesystem (BeFS stores them in the inode structure for the file).Įverything is layered on top of this. NTFS, like BeFS, is basically a key-value store, with two ways of storing values. NTFS is a lot like BeFS: the folks talking to the filesystem team didn’t provide a good set of requirements early on and so they ended up with something incredibly general.
