OK. I think you are saying that the POSIX specification sentence If either of the files dot or dot-dot are specified as the basename portion of an operand (that is, the final pathname component) or if an operand resolves to the root directory, rm shall write a diagnostic message to standard error and do nothing more with such operands. conflicts with your prior use of the GNU rm --one-file-system extension as a shorthand for "find . -xdev -delete". Since GNU already has a --no-preserve-root extension, as you pointed out, I don't see what would stop them from adding another extension to permit GNUrm -rfx . to work. Perhaps you should come up with an appropriate syntax for it and submit a patch to the GNU coreutils maintainers. This is not related to bash. (Wow, how did we get here from "-e does not take effects in subshell"?)
