Flag --log is broken?

[tiqwab]

I found that the current youki can't write logs to a file.

$ sudo ./youki --log /tmp/youki.log create -b ~/workspace/tmp/mycontainer mycontainer

# file is created, but empty
$ ls -l /tmp/youki.log
-rw-r--r-- 1 root root 0 Nov 14 12:45 /tmp/youki.log

youki uses env_logger, but env_logger::Target::Pipe is broken according to rust-cli/env_logger#208.

I had noticed this too, but hoped that env_logger fixes this soon^TM.

Hmm this is unfortunate... I was hoping env_logger to be more stable and save us the boilerplate. Let me take this issue and see if we should just revert to having our own logger implementation.
