Installing the .deb package with any Debian version before 12 will result in the following error:

~$ sudo dpkg -i oink.deb
dpkg-deb: error: archive 'oink.deb' uses unknown compression for member 'control.tar.zst', giving up dpkg: error processing archive oink.deb (--install): dpkg-deb --control subprocess returned error exit status 2 Errors were encountered while processing: oink.deb

The fix is to compress with .xz

I am using your excellent work on an alpine vm which uses openrc rather than systemd. Perhaps you'd like to include this working init script for others similarly (Gentoo, etc) situated:

#!/sbin/openrc-run

##/etc/init.d/oink_ddns

name="oink_ddns"
cfgfile="/etc/oink_ddns/config.json"
command="/usr/bin/oink"
pidfile="/run/oink_ddns/oink_ddns.pid"
command_background="yes"

start_pre() {
checkpath --directory --owner root:root --mode 0775
/run/oink_ddns
}

This file and:

rc-update add oink_ddns default

does the job

It would be nice if there were an option to run Oink on a systemd timer launching only at update intervals rather than running as a daemon that calls sleep() on a loop.

Not running as a daemon would reduce the overall memory footprint on machines where it runs, requiring memory only when an update is being performed.

Thanks for making this handy DDNS tool!

Running on a very clean Debian 12 installation, snap appears to install the package and dependencies with no issues

root@debianTest:~# snap install --beta oink
2023-12-27T15:23:55-07:00 INFO Waiting for automatic snapd restart...
oink (beta) 1.0.1 from Ricard Lado (rlado) installed

However there is no directory or config file created at /etc/oink_ddns/ and there is no service created for oink_ddns:

root@debianTest:~# systemctl status oink_ddns
Unit oink_ddns.service could not be found.

Critically, the snap directory for oink doesn't contain anything

root@debianTest:~# tree snap
snap
└── oink
    ├── 14
    ├── common
    └── current -> 14

5 directories, 0 files

Otherwise this is a very cool tool, I think a snap package for distribution is an excellent way to go!
