While it clearly worked for you with openrc it is broken on sysvinit as
the example /usr/share/doc/nftables/examples/sysvinit/nftables.init has
this:

# Default-Start:
# Default-Stop:      0 1 2 3 4 5 6


in the LSB header, not the required:

# Default-Start:    S
# Default-Stop:     0 1 6

It stands for Net Filter Tables. It handles more than iptables (also
ip6tables, arptables and ebtables) and it's been developed by the Net
Filter team, hence the name. The binary is also nft.

It is obviously coming in very slowly (it's been around for at least 5
years). And users are still translating it back to iptables syntax
using iptables-legacy.

Beowulf still installs with iptables. Buster uses nftables.

Firewalld can use nftables as a backend. UFW can't.
