Hi, I am trying to get devfs to only show me a few devices but I can't seem to get devfs to recognise the new rules that I create. devfs recognises some of the rules but not all of them: # devfs -m /path/to/jail rule showsets 1 2 3 4 8 9 10 11 Rules 12 and 13 are not recognised. If I try to set the devfs ruleset to 4 (for jail in /etc/defaults/devfs.rules) for the /dev mounted in the jail then add the rules and applyset everything works fine. When i try to start the jail I get the following: viper:/usr/jails# /etc/rc.d/jail restart myjail Configuring jails:. Starting jails:devfs rule: expecting argument for include devfs rule: expecting argument for include /etc/rc.d/jail: WARNING: devfs_set_ruleset: you must specify a ruleset number devfs rule: ioctl DEVFSIO_SAPPLY: No such process I'm not sure why I get the first warning, it doesn't seem to prevent anything from working in my other jails. The second warning is because devfs can't find the rule set (defined as jail_avr_devfs_ruleset="devfsrules_jail_avr" in rc.conf) Can anyone shed any light on this for me I can't seem to figure it out. Googling doesn't seem to help me either viper:~$ uname -a FreeBSD viper 7.0-RELEASE-p12 FreeBSD 7.0-RELEASE-p12 #0: Wed Oct 7 13:39:21 BST 2009 VIPER i386 The contents of my devfs.rules is below # cat /etc/devfs.rules # # Devices for xserver in jail # [devfsrules_unhide_xorg=8] add path agpgart unhide #add path console unhide add path dri unhide add path 'dri*' unhide add path io unhide add path mem unhide #add path pci unhide add path tty unhide add path ttyv0 unhide add path ttyv1 unhide add path ttyv8 unhide [devfsrules_unhide_cam=9] add path 'da*' unhide add path 'cd*' unhide [devfsrules_unhide_kmem=10] add path kmem unhide # # This allows to run a desktop system in a jail.
