NAME
devfs - Devices file system
DESCRIPTION
The devfs filesystem manages a name space of all devices under the
Solaris operating system and is mounted during boot on the /devices
name space.
The /devices name space is dynamic and reflects the current state of
accessible devices under the Solaris operating system. The names of all
attached device instances are present under /devices.
The content under /devices is under the exclusive control of the devfs
filesystem and cannot be changed.
The system may be configured to include a device in one of two ways:
o By means of dynamic reconfiguration (DR), using, for exam‐
ple, cfgadm(8).
o For devices driven by driver.conf(5) enumeration, edit the
driver.conf file to add a new entry, then use update_drv(8)
to cause the system to re-read the driver.conf file and
thereby enumerate the instance.
The device may be attached through a number of system calls and pro‐
grams, including open(2), stat(2) and ls(1). During device attach, the
device driver typically creates minor nodes corresponding to the device
via ddi_create_minor_node(9F). If the attach is successful, one or more
minor nodes referring to the device are created under /devices.
Operations like mknod(2), mkdir(2) and creat(2) are not supported in
/devices.

NOTES
The /devices name space cannot be unmounted.
All content at or below the /devices name space is an implementation
artifact and subject to incompatible change or removal without notifi‐
cation.
