Manual invoke #8

Is is possible to have an option to run vdev manually? As we've talked on the Devuan mailing list. Vdev runs and populates /dev from sysfs during boot time and exits.

Root can anytime call vdev to patch/update /dev.

Thanks!

This should be possible by creating a separate Linux back-end that simply exits once the initial sysfs devices get processed. Thanks for opening this request!

It's still lightly tested, but this should be implemented as of commit 47d166eaf68e5e6fd58da5e4a7176493660d9843.

Re-opening...forgot to add code that removes unused device nodes across invocations. Shouldn't be too hard, though.

Still lightly tested, but this is now implemented in 5fb243fd845da81099fdf28f572b58fafceb721f. All devices that are not in /dev but were added will be added, and all devices that are unplugged will be removed from /dev. This lets you effectively "patch" your /dev, to make it consistent with the state of your computer's hardware.

To use this feature, run vdevd --once.

Thanks jude. I'm trying to write an init script now. I'll send a pull request when I'm done, and I might have a couple questions on the way.
