I need to change the ownership of my 2nd serial port for nut to work properly with my ups. I am using devfs which is enabled at boot. I can set the ownership with a command like: chown root.nut /dev/tts/1 That works no problem, but I need it to continue to have those ownerships when the computer is rebooted. Now, I have looked in /etc/devfs but there are several files here which it seems I can edit. For example there is a file called /etc/devfs/perms, but this seems to register old style device names and is used by devfsd. There is also another file called: /etc/devfs/conf.d/devfs_extra_perms And it seems most probable since it has the following lines in it: # serial devices (temporary - later I will make a hack to the MAKEDEV parsing) REGISTER ^tts/[^/]*$ PERMISSIONS root.dialout 0660 But again I am not sure if this is where I need to change it since it seems to be a file that is generated by a package and will thus be overwritten later when the package is updated. Also, I would prefer to change the devfs configuration rather than just the devfsd one. Since I may be able to do without devfsd if I can get everything configured properly. Can someone tell me the correct Debian way of changeing device ownerships permanently. Cheers. Mark.
