unbound hangs at bootup
Unbound hangs rather than starting, causing openrc's startup to hang, preventing bootup completion, and therefore preventing a shell prompt.
Normality is resumed by uncommenting this line in /etc/conf.d/unbound:
supervisor=supervise-daemon
(I got a shell prompt by appending init=/bin/sh to the kernel commandline, and using e.g. mount -o remount,rw / ).
Whilst recovering, I had the following observations:
- openrc's softlevel= kernel commandline options don't seem to have any effect in Alpine
- openrc doesn't seem to have any timeout on service startup
