I’m trying to configure Dynamic DNS (RFC2136) on my bind server, but can’t understand how should i manage the zonefiles.
Actually the zonefiles are in the /nix/store, and obv they’re read-only files, but dynDNS needs to dynamically edit those zonefiles (let’s encrypt, through lego-acme, for examples).
I managed to setup dynDNS, but when i try to test it using nsupdate i got those errors:
stdio.c:29: unexpected error:
Aug 30 16:58:39 kelpie.garr.cloud.pa. named[969906]: unable to convert errno to isc_result: 30: Read-only file system
Aug 30 16:58:39 kelpie.garr.cloud.pa. named[969906]: /nix/store/xgxi3vkw0gsqw68bj5vqhfj3brbs5ymg-foo.me.zone.jnl: create: unexpected error
And i guess that those are related to the zonefile in the /nix/store being read-only…
