In https://gitlab.com/kalilinux/packages/nmap/-/commit/b6f4293f7f9c4099e38e5958ec37075c9e6cfdf4 a wrapper was added to allow nonroot users to run nmap with the necessary filecaps to do raw sockets, etc. without being root. Great!

However... it breaks nmap --resume:

$ nmap --resume foo.gnmap
Cannot use --resume with other options. Usage: nmap --resume <filename>
QUITTING!

This is because the wrapper injects the --privileged argument whenever run as non-root:

#!/usr/bin/env sh

set -e

if [ $(id -u) -eq 0 ]; then
exec /usr/lib/nmap/nmap "$@"
else
exec /usr/lib/nmap/nmap --privileged "$@"
fi

...Which is why nmap gets started with more args than it expected. But resume mode will find and respect that --privileged was in the saved command-line, so we don't need to add it. Since --resume must be the first arg, we can easily just test for it:

if [ $(id -u) -eq 0 -o "$1" = "--resume" ]; then

That seems to work fine here.
