On 10th Oct 2013 in revision r256256 FreeBSD has changed
rc.d script for running jails. The new version uses configuraion from /etc/jail.conf file instead of /etc/rc.conf
entries. This change exposed a problem where devfs was not importing default rules anymore - therefore
option devfs_ruleset was ignored.
I came across that issue yesterday and wasted some time trying to figure out what the root cause was. The problem exists
because new rc.d script is no longer causing side effect of loading default rules from /etc/defaults/devfs.rules. This
issue was discovered some time ago and in
revision r231194 fix was commited by adding new rc.conf
option devfs_load_rulesets defaulting to NO. Setting the options to YES in /etc/rc.conf and running
service devfs restart
will bring the defaults from /etc/defaults/devfs.rules and your local changes from/etc/devfs.rules to life just like
the old side effect did. During migration to /etc/jail.conf don’t forget to insert rule number instead of its name
in devfs_ruleset option!
