Only root can use this option. I would like to see the Linux behaviour under FreeBSD, being able to allow non-root users to use allow_other/allow_root option. I then also think that it could be interesting to support allow_root : allow_root This option is similar to allow_other but file access is limited to the u= ser mounting the filesystem and root. This option and allow_other are mutually exclusive. I need Fuse FS mounted by non-root users to be available to root (at least = the very first dir). I then use this dirty quick tweak : --- sys/fs/fuse/fuse_internal.c.orig +++ sys/fs/fuse/fuse_internal.c @@ -142,7 +142,7 @@ int denied =3D fuse_match_cred(data->daemoncred, cred); - if (denied) { + if (denied && (cred->cr_uid)) { return EPERM; } } Would then be nice to be officially supported.
