Learn to read. Linux has never allowed that. Most of the Unix systems do not allow that. Original _did_ allow that, but at the cost of very easily triggered fs corruption (and it didn't have things like rename(2) - it _did_ have userland implementation, of course, in suid-root mv(1), but that sucker had been extremely racy and could be easily used to screw filesystem to hell and back; adding rename(2) to the set of primitives combined with multiple links to directories leads to very nasty issues on _any_ system). - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
