> One thing to be aware of: the .lsrules format from Little Snitch on macOS is not compatible with the Linux version.

Why?

Just because I did not port the parser for it to Rust. And I thought that the lsrules format is rare for blocklists. If there is popular demand, we can add it.

You should add this feature.

Probably because it relies on eBPF rules on Linux?
