permissions of /proc/tty/driver



Hi.

This may not be stritly on topic, but I couln't figure out a better place to ask:

During the packaging of an application, I have the following problem:
I would like to run a daemon as non-root. The daemon likes to (continually) check /proc/tty/driver/usbserial to see whether or not interesting USB devices are connected. The permissions of this actual file is (on a kernel compiled from Debian's kernel-source-2.6.10) 0444, so this isn't a problem. However, the parent directory /proc/tty/driver is 0500. I'm not sure whether this is related to Debian DSAs 358 or 423 (where /proc/tty/driver/serial is mentioned as leaking sensitive information), to me the contents of usbserial look innocent enough.
Do you have any hints on what might be a good solution?

Kind regards and thanks in advance

T.
