Xattrs do not work
I can't get xattrs to work, either with overlayfs which uses xattrs to track filesystem changes, or directly with getfattr:
$ cd mount
$ touch file
$ getfattr file
getfattr: file: Operation not supported
Tested with lite and full formats with default parameters, under both btrfs and tmpfs backing filesystems.
--trace doesn't log anything when using getfattr.
Currently securefs only supports xattr on macOS, due to the extensive usage of xattr on this OS. Are you trying on Linux?
If you have serious needs for xattr on Linux, rather than just toy with it, please let me know. I'll implement it in the following versions.
Yes I'm on linux, I thought the docs meant macOS has special handling of xattrs, not that only macOS supported them, sorry.
My use is to mount compressed read-only filesystems and add a writable layer with overlayfs, which requires xattrs to track things like deleted files.
For now, i'm migrating those parts of my securefs mount to gocryptfs, as they aren't very fingerprintable and thus don't need the extra security. Thanks for considering support!
So the layering is securefs/gocryptfs ➡️compressed readonly filesystem➡️overlayfs?
