[smb/afp] group permissions executable bit set by default: chmod g-x does not remove
How can I mount on OS X with file permissions perserved? Which turns into, how can natatalk be configured to allow chmod changes and not default to group executable permssions? Summary: # -- on OS X in AFP mount (e.g. /Volumes/share) --- umask 022 # no effect touch test stat -f '%Sp' test # -rw-rwxr-- # why is the group exec bit set!? # -- try to change permissions, no luck -- chmod g-x stat -f '%Sp' test # -rw-rwxr-- # no error but still g+x # -- change permissions on local filesystem (or nfs mount) --- ssh user@NAS chmod g-x /data/share/test stat -f '%Sp' test # -rw-rw-r-- # success! permissions reflected within AFP mount I'd like to expose a share to OS X clients over afp or smb such that file permissions are preserved -- so file permissions on nfs mounts and afp mounts look the same. OS X doesn't do nfs well and I cannot find a way to enable unix extensions for samba, so I'm looking at afp (netatalk). Files created on AFP mounts always have the group executable bit set. chmod has no affect (chmod g-w, chmod g-x, chmod u+x, ... no change). Howver, AFP mount file permissons do reflect any changes made on the NAS share locally or on NFS mounts. I think this is similiar to https://community.netgear.com/t5/Using-your-ReadyNAS/AFP-Mount-Point-Permissions-Solved/m-p/695352#M2505
