cd91ad28b0 Add common KMS modules to the releng initramfs image.
On machines with common graphics chipsets (radeon, intel, nvidia), enable
KMS early. Downloading images from a remote server can take time, better
view the status with a nice resolution.

76dea1654e [archiso] Add PXE NFS support
It add support for using *.sfs images via NFS.

It must be located after archiso_pxe_nbd in mkinitcpio.conf, in that way
NBD is the default.

New boot parameters:

    archiso_nfs_srv=IP:/path
         Set the NFS IP and path. Accepts ${pxeserver} as IP.

    archiso_nfs_opt= Sets NFS mount opts (comma separated)
                    Defaults to:
                      port            = as given by server portmap daemon
                      rsize           = 1024
                      wsize           = 1024
                      timeo           = 7
                      retrans         = 3
                      acregmin        = 3
                      acregmax        = 60
                      acdirmin        = 30
                      acdirmax        = 60
                      flags           = hard, nointr, noposix, cto, ac

8eb4c624dc [archiso] Add archiso_pxe_curl hook
Its add support for downloading the ISO image via HTTP/FTP with curl or download *.sfs files.
The files are downloaded on /run/archiso/curlspace (tmpfs) and setup a loop dev from it
(like in archiso_loop_mnt) in the ISO case, or just do a bind mount to
/run/archiso/bootmnt in the other case.

This hook must be located after archiso_pxe_nbd in mkinitcpio.conf, in that way
NBD is the default.

New bootparm:
* archiso_curl_url=(first form)
    archiso_curl_url=http://192.168.0.7/archlinux/iso/archlinux.iso (absolute form)
        Use an absolute URL. Fetch the entire ISO
    archiso_curl_url=ftp://${pxeserver}/archlinux/iso/archlinux.iso (relative form)
        Use the as IP the same server where PXE reside.  Fetch the entire ISO

* archiso_curl_url=(second form)
    archiso_curl_url=http://192.168.0.7/archlinux/iso/unpacked (absolute form)
        Use an absolute URL. Where unpacked (an example name) is a directory where
        ${archisobasedir} ("arch" by default) is located with all *.sfs.
        This fetch only needed files.
    archiso_curl_url=ftp://${pxeserver}/archlinux/iso/unpacked (relative form)
        Use the as IP the same server where PXE reside. Where unpacked (an example name)
        is a directory where ${archisobasedir} ("arch" by default)
        is located with all *.sfs. This fetch only needed files.

* curlspace_size= Set a size for a tmpfs filesystem where files are downloaded.

1edaf15cef [archiso] Split archiso_pxe_nbd in two hooks.
One hook only setup the network device (archiso_pxe_common) the other
setup the NBD client (archiso_pxe_nbd).

New bootparam:
    archiso_pxe_srv=IP
        Allow to set an IP different from the PXE server.

59ad1113d9 [archiso] Add archiso_shutdown hook.
STATUS: Working (std boot, loop_mnt, pxe) with copytoram=[y|n].

NEEDS: initscript > 2011.07.3, mkinitcpio > 0.7.2, mkinitcpio-busybox > 1.18.5-1

Purpose: we need this for propertly unmount $cow_device,
used for persistent dm-snapshot devices.

This hook is based on work from Tom Gundersen[#1],
but adapted for archiso things (specially the shutdown script)

85d243ff58 [archiso] Use dm-snapshot instead of aufs2 (A.K.A. "The Big Commit")
* Use device mapper + snapshot module, instead union layer filesystem.
  * A block-level approach vs vfs-level.
  * No more unofficial (Linux) things.
  * More memory is needed.
* Refactor mkarchiso.
* Refactor hooks/archiso.
* Fix install/archiso_pxe_nbd
  (due recent change in mkinitcpio-0.6.15 on checked_modules()/all_modules())
  [Thanks Dave for the improved workaround]
* New configs/releng to build official images.
  * Works with a Bash script instead of Makefile.
    (better control and easy to maintain)
* Remove configs/syslinux-iso.
* Remove archiso2dual script. Integrate functionality in configs/releng.
* New configs/baseline to build the most basic live medium or use as template.
* New README (draft). [Thanks Dieter for fixing english grammar]
