Create
/var/tmp/root/.config/awesome/rc.lua:
Code:
package.path = "/var/tmp/root/.config/awesome/?.lua;" .. package.path
dofile("/etc/xdg/awesome/rc.lua")
Then copy to
/var/tmp/root/.config/awesome/ any file from
/etc/xdg/awesome, change the copy, reload (restart) awesome. Modified copy will take precedence.
