# Note: sudo -i creates a login shell for someUser, which implies the following:
# - someUser's user-specific shell profile, if defined, is loaded.
# - $HOME points to someUser's home directory, so there's no need for -H (though you may still specify it)
# - the working directory for the impersonating shell is the someUser's home directory.
