Sometimes, for various reasons, user may want to reboot a device. This is a common task and it makes sense to support it with something common like a procd.
Right now both: LuCI and LuCI2 implement this feature on their own with luci-rpc-luci2-system reboot and luci-rpc-sys reboot. This leads to code duplication and situation may become even worse with more software controlling system with ubus. Once we get this patch in place we may consider switching LuCI and LuCI2 to this new method. Signed-off-by: Rafał Miłecki <zaj...@gmail.com> --- I wrote a simple app for my own purposes (and a bit of fun) that uses ubus over HTTP. I wanted to add support for rebooting device and I hit this issue. I didn't want another deamon or rpcd plugin adding reboot support so I decided to come with this procd patch.
