Dear Peter (BTW; Hans Peter sounds very Danish - any relatives there?) I acknowledge the security issues, but my focus is the user on a stand-alone computer, not the network-box. My knowledge about permissions, network-hacks etc. is fine - I have written 11 books about Linux :) I have tried to read the README* files in the source without any luck. Could you guide me how to set this owner flag? I have tried to add to /etc/auto.misc a line usb -fstype=auto,owner :/dev/sda1 but this will still leave /misc/usb owned by root:root I can do the usb -fstype=auto,uid=500,gid=500 :/dev/sda1 but this will only give user #500 the read/write-access. Assume that we like my wife, kid, and dog :) to have writeaccess - whoever mounts the device (typically a vfat formatted device).
