And for example Debian does not use it at all. that's why it was a hack. i think it reasonable that if there is no debug info to first look for the file name itself, and then look for the file name with a .debug suffix. so `gdb prog` where prog is found at /usr/bin/prog would default to /usr/lib/debug/usr/bin/prog followed by /usr/lib/debug/usr/bin/prog.debug (and obviously /usr/lib/debug/ is the existing configurable setup and not a hardcoded path). i'm thinking of the fallback/default behavior here. none of this would preclude the existing explicit options that gdb has available. -mike
