CoreOS mdadm RAID1 for ROOT

• Setup SoftwareRAID for the CoreOS root partition without data-loss.
• Only for ext4!
• The Trick is to use the right volume label and fs-types :)
• We assume CoreOS is on /dev/sdaX and the second RAID Device is /dev/sdb
• Drawback: only / gets mirrored, Node goes down when sda fails

1. Boot into any recovery system like Grml
2. If not already done: install CoreOS

Subject: [PATCH] main: keep fd handlers in list

Experimental code in order to try to solve
sockets for Windows. On windows the "int fd" is actually
of type "SOCKET fd" and the range goes from 0 to very large.

ref #61
