acmetool is an alternative client for Let's Encrypt.
(https://github.com/hlandau/acme/)
It stores the certificates etc. in the following directory layout:
/var/lib/acme/live/<domain> -> ../certs/<hash>
/var/lib/acme/certs/<hash>/cert
/var/lib/acme/certs/<hash>/chain
/var/lib/acme/certs/<hash>/privkey -> ../../keys/<hash>/privkey
/var/lib/acme/certs/<hash>/url
/var/lib/acme/certs/<hash>/fullchain
/var/lib/acme/keys/<hash>/privkey
This patch adds the needed permissions to the ssl_certs and ssl_keys
abstractions so that the certificates can be used.
Acked-by: Seth Arnold <seth.arnold@canonical.com> for trunk, 2.10 and 2.9.
