Yes. FreeBSD supports nosuid mounts. With ZFS, it's even an inheritable property on the dataset. In either case, just running `mount` and looking for the mount-point where the binary lives should reveal it. Eg: # mount | grep music cast/media/music on /mnt/cast/media/music (zfs, local, noatime, noexec, nosuid, nfsv4acls) # zfs get setuid cast/media/music NAME PROPERTY VALUE SOURCE cast/media/music setuid off inherited from cast/media Hope this helps with debugging, -Phil -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
