The mdevd-coldplug program

mdevd-coldplug performs a coldplug: it scans /sys for all registered devices a uevent manager would want to perform actions on, and tells the kernel to generate uevents for all these devices.

Interface

     mdevd-coldplug [ -s slashsys ]

• mdevd-coldplug scans /sys for devices.
• For every suitable device it finds, it tells the kernel to generate an event. If a device manager such as as mdevd is listening to the netlink at this point, it will pick up the series of events.
• mdevd-coldplug exits when it has finished scanning.

Options

• -s slashsys : assume the sysfs pseudo-filesystem is mounted on slashsys. Default is /sys.

Exit codes

• 0: success
• 111: system call failed

Notes

• mdevd-coldplug is a short-lived program, just like mdev -s or udevadm trigger.
