initramfs-tools: update to 0.99.111.
- Removed NFS/network boot, it never worked anyway. - Removed support for booting from UBIFS and exotic platforms. - Create busybox links at initramfs creation time. - Panic if mounting devtmpfs fails, udev requires this now. - Mount devpts filesystem once udev has been started. - Move all mounted filesystemd to the real root before switching root.
