Restart reminder

Reminds you to reboot after you upgraded your kernel. With Arch Linux old kernels aren't kept after an upgrade.

import os
import os.path

from i3pystatus import Status, IntervalModule

class RestartReminder(IntervalModule):
    settings = required = ()
    
    def run(self):
        if os.path.exists("/lib/modules/" + os.uname().release):
            self.output = None
        else:
            self.output = {
                "full_text": "Reboot required!",
                "color": "#FF0000",
            }
            
#status = Status(standalone=True)
# ...

status.register(RestartReminder())
