your patch broke it. eval rs=\$1 means rs will be set to the literal $1, while
it should expand to the ruleset number, using the ruleset name, because
devfs_rulesets_from_file sets:
eval $rulename=\$rulenum
Something else is wrong. Set rc_debug="YES" in /etc/rc.conf then
/etc/rc.d/jail start example
to trace how the rulesets are evaluated.
