It's only a matter of time before that system is toast. The only question
is whether someone decides to take advantage of the giveaway of root
permissions for a while before toasting it.
(Oh, Tim --- why he sorted it: if you try it when there's a path like
`/foo/core/bar/baz/core', it'll complain because /foo/core will get `rm
-rf'-ed and then later it will try to `rm -rf /foo/core/bar/baz/core'. I
can think of another `find' option or two that would make more sense as an
alternative, if he really wants to include directories named `core'.)
I'll say this much: if I caught anyone running this on one of ECE's
supported boxes, they'd gain a few broken fingers and quite possibly *lose*
their accounts in ECE. (Yeah, some of these folks get --- and need ---
root.) Oy.
