[Bug]: Symlinks not support for server config

[axelson]

What did you expect to happen?

I manage my system configuration by keeping my configuration files in a git repo inside /home/myuser/config. So I tried setting up /etc/atuin as a symlink to /home/myuser/config/atuin-server

Note: my server is setup with systemd: https://docs.atuin.sh/self-hosting/systemd/

What happened?

I got various errors (I initially tried symlinking the entire /etc/atuin folder but I also tried only symlinking the /etc/atuin/server.toml file)

Error when /etc/atuin is a symlink:

Instead I'd expect to not get an error in either case
