Please document required system tools

[piotr-dobrogost]

For example update-systemd-resolved.sh uses ip command which on Fedora is located at /usr/sbin/ip yet README suggests setting PATH to /usr/bin.
Generally, in order to establish how PATH should look like one should know which system tools are being used.

@piotr-dobrogost,

Thank you for the bug report. Appreciated, the PATH environmental variable, as provided, won't work on RedHat-based distributions. This was developed on an Arch-based system, which does away with the bin/sbin split, as well as usr/no-usr structure (everything is in /usr/bin), which is also the same way that Debian is going (where I know this script has also been tested as-is so far).

I'll fix the documentation and issue a new release in the next few days.

On Debian systems, bash is put in /bin, not in /usr/bin

@mgu
And /usr/bin is not symlinked to /bin?

On my Debian Stretch, /bin/bash is a regular file and there is no /usr/bin/bash
