584813e214 Used MINIO_PROFILE_DIR for saving profile information of a minio server (#1722) 
To specify the directory where profiling information should be saved
  ```
    export MINIO_PROFILE_DIR=/path/to/profile/dir
  ```
By default, profiling information would be saved in a directory created
using ioutil.TempDir, which would be displayed in stdout on starting the
minio server.

e4240aa58f XL/objects: Initialize format.json outside of erasure. (#1640) 
Fixes #1636

New format now generates a UUID and includes it along with
the order of disks. So that UUID is the real order of disks
and on command line user is able to specify disks in any order.

This pre-dominantly solves our dilemma.

f5dfa895a5 Exit with error code if minio server fails to start (#1704) 
This commit replaces the call to `errorIf` with `fatalIf`, so that the
minio server exits with an non-zero exit status if something fails, e.g.
the port was already openend by another process.
