Please make openbsd-netcat the default netcat as gnu-netcat has no v6

Is it possible for Arch Linux repository maintainers to change the default provider of a package?

[root@f ~]# LC_ALL=C.UTF-8 pacman -S netcat
:: There are 2 providers available for netcat:
:: Repository extra
   1) gnu-netcat  2) openbsd-netcat

Enter a number (default=1): 2

gnu-netcat really shouldn't be the default as it is more than 21 years old and has no IPv6 support. openbsd-netcat should be the default. Is this possible to change or is it alphabetically sorted?

I'll try to look into it, from a first glance it should either be dropped or made ranking behind the openbsd variant.

Fwwi, nc (openbsd), netcat (gnu) and ncat (nmap) are not fully compatible implementations of the same concept.
A generic dependency will only work for basic invocation by the client process and if any user has some local scripts depending on gnu-netcat, simply replacing that w/ nc can cause weird failure b/c of colliding parameters (notably -t) or missing features.

You're almost looking at a java-like situation…

Compatible w/ all three:
https://github.com/marlam/msmtp/blob/ma … tpq/msmtpq has "nc -vz"
https://github.com/ugoviti/synbak/blob/ … s.sh#L1436 checks for netcat or nc and only uses "-w"

Hard-depends on openbsd-netcat:
https://archlinux.org/packages/extra/any/cloud-init/
https://archlinux.org/packages/extra/x86_64/libvirt/

Open question: https://archlinux.org/packages/extra/x86_64/zed/

The rest are make/check dependencies.
