1. Get delete working for my /etc/hosts editor.

2. Daemonize this program to be started up by systemd.
|

- As part of daemonization, remember and remove added hosts on teardown.

4. As part of daemonization -- only block hosts within a time limit.
|
||||
- Sleep, wakeup, check if time has passed or not, block/unblock host,
