Originally created by @tovine on GitHub (May 16, 2018).

I noticed that dehydrated refuses to run without sudo installed if DEHYDRATED_USER is set - why is that?
The same feature (restarting the script as a different user) is also perfectly doable using the su command: su $DEHYDRATED_USER -s /bin/bash -c "${0} ${ORIGARGS}"; the only difference I can see immediately is the option to explicitly specify the group to run as.

While sudo may be more feature-complete in some respects, su is "guaranteed" to be present in mostly any system you would run on and IMO should at least be provided as a fallback if sudo is not found.

I can probably make a PR for it if you want me to.

Using sudo does allow for a user switch without the need for a password (if configured). Also the group option might be needed by some people. Nobody forces you to use the dehydrated integrated sudo operation, you could always just use su yourself.
