Profpatsch 4a7f99d55d treewide: with stdenv.lib; in meta -> with lib;
Part of: https://github.com/NixOS/nixpkgs/issues/108938

meta = with stdenv.lib;

is a widely used pattern. We want to slowly remove
the `stdenv.lib` indirection and encourage people
to use `lib` directly. Thus let’s start with the meta
field.

This used a rewriting script to mostly automatically
replace all occurances of this pattern, and add the
`lib` argument to the package header if it doesn’t
exist yet.

The script in its current form is available at
https://cs.tvl.fyi/depot@2f807d7f141068d2d60676a89213eaa5353ca6e0/-/blob/users/Profpatsch/nixpkgs-rewriter/default.nix

dhcping sends either a DHCPREQUEST or DHCPINFORM packet to the server
and waits for an answer. Then, if a DHCPREQUEST was send, it will send
a DHCPRELEASE back to the server.
This program should be installed setuid root or ran by root only, as it
requires the privileges to bind itself to port 68 (bootpc). Root
privileges are dropped as soon as the program has bound itself to that
port.
