From: bas on 25 Mar 2010 16:29 Can't write to usb devices as a non-root user on 7.2-stable. Have in /etc/devfs.conf: perm da* 0660 own da* root:operator in /etc/devfs.rules: [local=20] add path 'da*' mode 0660 group operator in /etc/rc.conf: devfs_system_ruleset="local" in /etc/sysctl.conf vfs.usermount=1 A user in group operator can mount usb devices, but cannot write to them. The mount point, e.g. /home/someuser/mnt is always set to mode 744 and user root:wheel. What did I miss?

That is the only way it is going to work. -- Torfinn Ingolfsen, Norway

I wonder if he's got that part right... -- Use the BIG mirror service in the UK: http://www.mirrorservice.org

Then the user does 'mount /dev/ da0s1a mnt' after which mnt is owned by root:wheel with mode 755. The user can cd to the external volume and read what is there, but not write to it. Unmounting the external volume returns mnt to user:user mode 755. |
