1) NTS keys are generated by letsencrypt/certbot and in Ubuntu are =
accessible to group ssl-certs.
I can add Chrony user _chrony to group ssl-certs, and verify that user =
can access the certificates.=20
Also, I added AppArmor exception to allow Chorny to access the keys.=20
Still Chrony won't be able to access the keys as Chrony seems to be =
stripping group permission from itself.

What is the valid path to making NTS work without actually =
copying/chown-ing keys on schedule? I would prefer to keep private keys =
in single place.=20

2) Will chrony see that keys are updated, or he will need to have keys =
reloaded in a script?
