The webserver is user name is "www-data" (I guess that's the Apache default now). It has its own group (also called "www-data"). So if the mount point has these owners and permissions... chown ${USER}:www-data chmod 750 ...that would do what I want, right? (owner: me, group: webserver, owner has rwx and group has r-x). In other words, I don't think making a new group adds anything I need. > You are suggesting the solution I offered above. I think you are on the > right track. With some testing you will get there. Thanks. I'll let you know if I get it. Also, I guess you are working on udev, so let me know if you figure it out. It seems like the udev rules have numbers that determine how early in the boot process they are implemented. Example subset: $ ls -l /lib/udev/rules.d/*usb* -rw-r--r-- 1 root root 552 Apr 21 2017 /lib/udev/rules.d/39-usbmuxd.rules -rw-r--r-- 1 root root 998 Sep 15 2017 /lib/udev/rules.d/40-usb-media-players.rules -rw-r--r-- 1 root root 40871 Feb 23 13:56 /lib/udev/rules.d/40-usb_modeswitch.rules -rw-r--r-- 1 root root 292 Jan 16 2018 /lib/udev/rules.d/55-ippusbxd.rules -rw-r--r-- 1 root root 692 Jun 22 07:55 /lib/udev/rules.d/73-usb-net-by-mac.rules -rw-r--r-- 1 root root 8126 Apr 24 06:06 /lib/udev/rules.d/77-mm-usb-device-blacklist.rules -rw-r--r-- 1 root root 2452 Apr 24 06:06 /lib/udev/rules.d/77-mm-usb-serial-adapters-greylist.rules So the fix I need might be as simple as finding the right rule, changing the number to a lower value and hardcoding user and group. Thanks again, Iznogoud! Mike
