5.14 /var/spool : Application spool data #
5.14.1 Purpose #
/var/spool contains data which is awaiting
some kind of later processing. Data in
/var/spool represents work to be done in the
future (by a program, user, or administrator); often data is deleted
after it has been processed.

5.14.2 Specific Options #
The following directories, or symbolic links to directories,
must be in /var/spool, if the corresponding
subsystem is installed:
| Directory | Description |
|---|---|
lpd | Printer spool directory (optional) |
mqueue | Outgoing mail queue (optional) |
news | News spool directory (optional) |
rwho | Rwhod files (optional) |
uucp | Spool directory for UUCP (optional) |
5.14.3 /var/spool/lpd : Line-printer daemon print queues (optional) #
5.14.3.1 Purpose #
The lock file for lpd,
lpd.lock, must be placed in
/var/spool/lpd. It is suggested that the lock
file for each printer be placed in the spool directory for that
specific printer and named lock.
5.14.3.2 Specific Options #
| Directory | Description |
|---|---|
printer | Spools for a specific printer (optional) |
5.14.4 /var/spool/rwho : Rwhod files (optional) #
5.14.4.1 Purpose #
This directory holds the rwhod information
for other systems on the local net.
Tip: Rationale
Some BSD releases use /var/rwho for this
data; given its historical location in /var/spool
on other systems and its approximate fit to the definition of
`spooled' data, this location was deemed more appropriate.
