The file has the format:
- <device regex> <uid>:<gid> <permissions>
- or @<maj[,min1[-min2]]> <uid>:<gid> <permissions>
+ [-]<device regex> <uid>:<gid> <permissions>
+or
+ @<maj[,min1[-min2]]> <uid>:<gid> <permissions>
+or
+ $envvar=<regex> <uid>:<gid> <permissions>
For example:
- hd[a-z][0-9]* 0:3 660
+ hd[a-z][0-9]* 0:3 660
The config file parsing stops at the first matching line. If no line is
matched, then the default of 0:0 660 is used. To set your own default, simply
create your own total match like so:
+
.* 1:1 777
You can rename/move device nodes by using the next optional field.
+
<device regex> <uid>:<gid> <permissions> [=path]
+
So if you want to place the device node into a subdirectory, make sure the path
has a trailing /. If you want to rename the device node, just place the name.
