MOUNT notifies when a filesystem is mounted REMOUNT notifies when a filesystem is mounted again UNMOUNT notifies when a filesystem is unmounted These events are asynchronous to the actual state of the event (though the data is recorded at a time when it is stable). The mount event is reported after the filesystem is mounted. However, in the interim it may be unmounted by another agent. Likewise, umount is called just before the mountpoint is finished tearing down. It may be remounted (or maybe if the process scheduling is wonky and devd gets to run before the last few steps are complete).

.Sh NAME
|
|
.Nm devd.conf
|
|
.Nd configuration file for
|
|
.Xr devd 8
|
|
.Sh DESCRIPTION
|
|
.Ss General Syntax
|
|
A
|
|
.Xr devd 8
|
|
configuration consists of two general features, statements
|
|
and comments.
|
|
All statements end with a semicolon.
|
|
Many statements can contain substatements, which are also
|
|
terminated with a semicolon.
|
|
.Pp
|
|
The following statements are supported:
|
|
.Bl -tag -width ".Ic options"
|
|
.It Ic attach
|
|
Specifies various matching criteria and actions to perform when
|
|
a newly attached device matches said criteria.
|
|
.It Ic detach
|
|
Specifies various matching criteria and actions to perform when
|
|
a newly detached device matches said criteria.
|
|
.It Ic nomatch
|
|
Specifies various matching criteria and actions to perform when
|
|
no device driver currently loaded in the kernel claims a (new)
|
|
device.
|
|
.It Ic notify
|
|
Specifies various matching criteria and actions to perform when the kernel
|
|
sends an event notification to userland.
|
|
.It Ic options
|
|
Specifies various options and parameters for the operation of
|
|
.Xr devd 8 .
|
|
.El
|
|
.Pp
|
|
Statements may occur in any order in the configuration file, and may be
|
|
repeated as often as required.
|
|
Further details on the syntax and meaning of each statement and their
|
|
substatements are explained below.
|
|
.Pp
|
|
Each statement, except
|
|
.Ic options
|
|
has a priority (an arbitrary number) associated with it, where
|
|
.Ql 0
|
|
is defined as the lowest priority.
|
|
If two statements match the same event, only the action of the statement with
|
|
highest priority will be executed.
|
|
In this way generic statements can be overridden for devices or
|
|
notifications that require special attention.
|
|
.Pp
|
|
The general syntax of a statement is:
|
|
.Bd -literal -offset indent
|
|
statement priority {
|
|
substatement "value";
|
|
...
|
|
substatement "value";
|
|
};
|
|
.Ed
|
|
.Ss Sub-statements
|
|
The following sub-statements are supported within the
|
|
.Ic options
|
|
statement.
|
|
.Bl -tag -width ".Ic directory"
|
|
.It Ic directory Qq Ar /some/path ;
|
|
Adds the given directory to the list of directories from which
|
|
.Xr devd 8
|
|
will read all files named "*.conf" as further
|
|
configuration files.
|
|
Any number of
|
|
.Ic directory
|
|
statements can be used.
|
|
.It Ic pid-file Qq Pa /var/run/devd.pid ;
|
|
Specifies PID file.
|
|
.It Ic set Ar regexp-name Qq Ar (some|regexp) ;
|
|
Creates a regular expression and assigns it to the variable
|
|
.Ar regexp-name .
|
|
The variable is available throughout the rest of
|
|
the configuration file.
|
|
If the string begins with
|
|
.Ql \&! ,
|
|
it matches if the regular expression formed by the rest of the string
|
|
does not match.
|
|
All regular expressions have an implicit
|
|
.Ql ^$
|
|
around them.
|
|
.El
|
|
.Pp
|
|
The following sub-statements are supported within the
|
|
.Ic attach
|
|
and
|
|
.Ic detach
|
|
statements.
|
|
.Bl -tag -width ".Ic directory"
|
|
.It Ic action Qq Ar command ;
|
|
Command to execute upon a successful match.
|
|
Example
|

|
|
.It Ic device-name Qq string ;
|
|
This is shorthand for
|
|
.Dq Ic match Qo Li device-name Qc Qq Ar string .
|
|
This matches a device named
|
|
.Ar string ,
|
|
which is allowed to be a regular expression or a variable previously created
|
|
containing a regular expression.
|
|
The
|
|
.Dq Li device-name
|
|
variable
|
|
is available for later use with the
|
|
.Ic action
|
|
statement.
|
|
.It Ic match Qo Ar variable Qc Qq Ar value ;
|
|
Matches the content of
|
|
.Ar value
|
|
against
|
|
.Ar variable ;
|
|
the content of
|
|
.Ar value
|
|
may be a regular expression.
|
|
Not required during
|
|
.Ic attach
|
|
nor
|
|
.Ic detach
|
|
events since the
|
|
.Ic device-name
|
|
statement takes care of all device matching.
|
|
For a partial list of variables, see below.
|
|
.It Ic media-type Qq Ar string ;
|
|
For network devices,
|
|
.Ic media-type

This is shorthand for
|
|
.Dq Ic match Qo Li subdevice Qc Qq Ar string .

.Pp
|
|
The following sub-statements are supported within the
|
|
.Ic notify

|
|
The
|
|
.Dq Li notify
|
|
variable is available inside this statement and contains, a value, depending
|
|
on which system and subsystem that delivered the event.
|
|
.Bl -tag -width ".Ic directory"
|
|
.It Ic action Qq Ar command ;
|
|
Command to execute upon a successful match.

|
|
Any number of
|
|
.Ic match

|
|

.Ss Comments
|
|
Comments may appear anywhere that whitespace may appear in a
|
|
configuration file.
|
|
To appeal to programmers of all kinds, they can
|
|
be written in C, C++, or shell/Perl constructs.
|
|
.Pp
|
|
C-style comments start with the two characters
|
|
.Ql /*
|
|
(slash, star) and end with
|
|
.Ql */
|
|
(star, slash).
|
|
Because they are completely delimited with these characters,
|
|
they can be used to comment only a portion of a line or to span
|
|
multiple lines.
|
|
.Pp
|
|
C-style comments cannot be nested.
|
|
For example, the following is
|
|
not valid because the entire comment ends with the first
|
|
.Ql */ :
|
|
.Bd -literal -offset indent
|
|
/* This is the start of a comment.
|
|
This is still part of the comment.
|
|
/* This is an incorrect attempt at nesting a comment. */
|
|
This is no longer in any comment. */
|
|
.Ed
|
|
.Pp
|
|
C++-style comments start with the two characters
|
|
.Ql //
|
|
(slash, slash) and continue to the end of the physical line.
|
|
They cannot be continued across multiple physical lines; to have
|
|
one logical comment span multiple lines, each line must use the
|
|
.Ql //
|
|
pair.
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
// This is the start of a comment. The next line
|
|
// is a new comment, even though it is logically
|
|
// part of the previous comment.
