mv command is not possible

[bwester]

Hi, thanks for looking at this project!

There's a good reason for the omission. The "mv" command is implemented using the "rename" operation on a file system, which POSIX says should be atomic. If interrupted, the source and destination paths must either be both unmodified or both changed. It's the only multi-file atomic operation in a POSIX file system, so a lot of software uses it to provide safe modifications.

When I started, Consul didn't support an atomic operation that would remove one key and add another. Rather than implement a non-atomic rename, I just disabled renames altogether. However, a "transaction" endpoint was added to Consul 0.7.0, making it possible to implement as a copy-and-delete operation.

I'll leave this issue open to document the feature request. I make no promise as to when I can build out this piece of functionality.

Many thanks for this (very) complete answer :)
