Don't cut essential tools without providing a superior replacement.
Things like traceroute and ping are essential for troubleshooting
network problems.

"traceroute" is provided nowadays by a separate package, not
net-tools. properly named "traceroute" [doh] it is what the rest of
the world also uses.

"ping" could be reimplemented to use the kernel's "ping" sockets
(socket(PF_INET, SOCK_DGRAM, IPPROTO_ICMP) ...) instead of the old
setuid/capability ways.. unfortunately the kernel has a barking mad
restriction in this socket type which means that by default, not even
root can use it. (go figure...)

Interesting feature. I'd love to get rid of the special privilege ping.
The permissions check via group and sysctl setting is kind of silly
