hi, on a couple of linux machines that are public workstations (i.e. a number of people have accounts and should be able to use the machines), i changed the permissions of /dev/cdrom to 0644 and /dev/fd0 to 0666 to enable the users to access the cdrom and floppy freely. the same (0666) was done for /dev/ttyS? - the users need access to the serial ports. a little while later, however, we had to discover that the permissions had been arbitrarily reset. /dev/fd0 went 0660 and got owned by the last user, group floppy. /dev/cdrom went 0600 <user>.disk /dev/ttyS0 went 0660 root.uucp ??? why does this happen? i noticed the /dev entries changing permissions and ownership whenever they felt like it. that's not how it's supposed to be. when i set fd0 to 0666 root.floppy, i intend it to stay like that until i change it. what is responsible for this change and how can i prevent it? thanks, martin madduck@madduck.net (greetings from the heart of the sun)
