Description Bryn M. Reeves 2007-03-02 09:58:42 EST
Description of problem:
/dev/raw/raw0 is char device major 162, minor 0, i.e. /dev/rawctl.

If a user attempts to bind this device udev will notice the new device & set up
a node for it. It also deletes /dev/rawctl at this point.

This is confusing for users. An error message indicating that raw0 should not be
bound is preferable.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. raw /dev/raw/raw0 /dev/<something>
2. ls -l /dev/rawctl

Actual results:
ls: /dev/rawctl: No such file or directory

Expected results:
/dev/rawctl still exists or the user gets a warning/error

Yeah, this is already known issue (that has been fixed in RHEL5).
Comment 5 Bryn M. Reeves 2007-04-06 06:11:35 EDT
And this is a RHEL4 bug - changing flags

Seems like bug 218315 has addressed this at the kernel level (2.6.9-55.2).
Comment 11 Karel Zak 2007-07-31 05:54:10 EDT
Well, the bug has been fixed in kernel and also in raw(8).
