28.Dt DEVFS.RULES 5
29.Os
30.Sh NAME
31.Nm devfs.rules
32.Nd devfs configuration information
33.Sh DESCRIPTION
34The
35.Nm
36file provides an easy way to create and apply
37.Xr devfs 8
38rules, even for devices that are not available at boot.
39.Pp
40For devices available at boot, see
41.Xr devfs.conf 5 .
42.Pp
43The format of this file is simple.
44Empty lines and lines beginning with a hash sign
45.Pq Ql #
46are ignored.
47A line between brackets denotes the start of a ruleset.
48In the brackets should be the name of the ruleset and its number,
49separated by an equal sign.
50.Pp
51Other lines are rule specifications as documented in
52.Xr devfs 8 ,
53in the section
54.Sx "Rule Specification" .
55These lines are prepended with
56.Dq Li rule
57and are passed to
58.Xr devfs 8
59by the startup scripts of the system.
60It is important to put path elements that contain
61.Xr glob 3
62special characters between quotes.
63.Pp
64Rulesets should have a unique name and number.
65.Pp
66All rules that follow a ruleset declaration belong to that ruleset, until a
67new ruleset is started.
68.Pp
69One custom ruleset has to be enabled in
70.Pa /etc/rc.conf ,
71otherwise it will not be applied to the
72.Pa /dev
73file system by the default system startup process.
74For example, to enable a
75.Dq Li localrules
76ruleset for the
77.Pa /dev
78file system, you would have to use something like this in your
79.Pa rc.conf
80file:
81.Bd -literal -offset indent
82devfs_system_ruleset="localrules"
83.Ed
84.Sh FILES
85.Bl -tag -compact
86.It Pa /etc/devfs.rules
87.It Pa /etc/defaults/devfs.rules
88.El
89.Sh EXAMPLES
90To make all the partitions of
91.Xr da 4
92devices readable and writable by their owner and the
93.Dq Li usb
94group, the following rule may be used:
95.Pp
96.Dl "[localrules=10]"
97.Dl "add path 'da*s*' mode 0660 group usb"
98.Pp
99The first line declares and starts a new ruleset, with the name
100.Va localrules
101and the number 10.
102.Pp
103To make all the
104.Xr uscanner 4
105devices accessible to their owner and the
106.Dq Li usb
107group, a similar rule may be used:
108.Pp
109.Dl "add path 'uscanner*' mode 0660 group usb"
