fosslinux d429c48d76 Update the linux kernel for sysb/c to 4.9.10.
- We do not use latest 4.9.x because it relies on a new version of
  binutils, while older versions do not. (Note: we should be able to go
  a bit newer but I didn't bother testing >50 versions to figure this
- We do not use newer kernel versions because they require one or more
  of (new perl, new binutils, new make, new gcc, new bison, new tar).
- sysb and sysc are updated to use the SATA (libata) subsystem (aka sda)
  instead of IDE-emulating SATA subsystem (aka hda) which is now
  available to us.
- While theoretically according to docs 4.9 should work OOTB with our
  version of binutils this is not the case, so we have to do a bit of
  (interesting) patching. But this does not break anything.
- Thankfully serial support in 4.9 is not screwed over like it is in 2.6
  so we can revert to that.
- 4.9 has the linux-libre project at our disposal, instead of gNewSense.
  So we use this. Unfortunatley that takes forever because we have to
  use sed because our version of gawk is too old/buggy. :( I plan to
  introduce very shortly 1. parallelism 2. 'sysc snapshot' which will
  start from sysc to avoid this. I do not want to use linux-libre
  tarballs because they make modificiations directly from this script
  (aka not easily verifiable, use the source!) and this script allows
  for much greater flexibility.
- We compile the initramfs ahead-of-build using the in-tree cpio
  generator instead of also building cpio to use less packages. We do
  NOT build the initramfs into the kernel like 2.6 (unsupported).
- Oh and fix a kexec-tools checksum.

fosslinux 5c88f1c87f Add sysb and sysc scaffolding.
Now that we have the Linux Kernel built, we move to a full-disk (rather
than initramfs) setup in sysc. However, we cannot assume the seed kernel
has support for mounting hard drives. So, first we need to kexec into
sysb, which is used as a jumping off point to create the hard drive for

Additionally, since 2.6.16 does not have support for on-demand initramfs
(initramfs must be built into kernel), we will have to rebuild the linux
kernel within sysb without the initramfs.

All of this process is not performed for chroot mode. Instead, we skip
sysb and jump straight to sysc, copying over appropriate data.

The python scripts have been changed slightly. Each sys* inherits
SysGeneral, which contains various functions which are not specific to
any sys* and simplifies those files. rootfs now also handles sysb and

bootstrap.cfg also gives an indication whether we are running in a
chroot to avoid attempting to kexec/mount within a chroot.

use branch v0.7 from kritis-linux and change settings
to be more i386-alike and add essential kernel feature
'flock' using latest kernel 3.18.140 from 3.18.x-branch
