Yes, two.
1. AHCP_NTP_SERVER is, in general, a space separated list of potential
servers. So instead of
ntp_server=$AHCP_NTP_SERVER
...
you should be doing
for ntp_server in $AHCP_NTP_SERVER; do
...
done
2. There's no need to ping the server -- the fact that the server is
unreachable at boot time doesn't mean it won't become available later.
Chrony is a well-written, robust piece of software. If a server doesn't
respond, chrony will send it requests with an exponentially decaying
interval -- first every 64 seconds, then every 128 seconds, etc. until it
reaches 1024 seconds (20 minutes).
So just pass the whole list of servers to chrony, whether they're
reachable or not, and trust chrony to do the right thing.
