d35d87f252 cleaner boot from loopmounted iso file
Currently, when booting loopmounted iso file, it is necessary to
specify not only img_dev and img_loop (which should be sufficient),
but also archisolabel or archisodevice. With this patch, archisodevice
is directly populated with the correct loop device, and it is not
necessary to specify the label when booting from loopmounted iso,
which makes for leaner and cleaner grub.cfg.

f21da59e81 flush ip addresses after copy to RAM
We received an IP address from DHCP server and configure it statically.
This is required if we continue to use network connectivity to access
the root device (for example via NBD or NFS).

The lease is not updated, though. This can cause trouble in networks
with low lease times. So let's flush the addresses if root filesystem
has been copied to RAM. A dhcp client in main system can handle the
network connectivity then.

b1011376cf explicitly detach loop device on umount and silent losetup error
Umount detaches the loop device automatically, but let's make it
explicit to be sure. Additionally losetup gives:

losetup: /dev/loop0: detach failed: No such device or address

This is kind of expected, let's silent the error message.

dced05a847 explicitly detach loop device on umount
I see cases where a stale loop device stays around and fills up my
partition as image file is still in use and does not get unlinked.

Explicitly detach loop device on umount to fix that.

a637bdb857 [archiso] Add optional OverlayFS support
This is the first attemp to test overlayfs in archiso.
The current dm-snapshot mode is keep and is enabled by default,
while the new mode is enabled via "-s sfs" to mkarchiso.
No new boot parameters are added, since archiso hooks detects
if the .sfs file is for dm-snapshot (airootfs.img inside)
or for overlayfs.
Persistence is supported in overlayfs mode using the same options
(cowlabel or cowdevice), but warning while in dm-snapshot mode,
only one file is used (airootfs.cow), in overlayfs mode internal
files for workdir/ and upperdir/ are allocated, so you can not use
VFAT or NTFS.

To test this, you need to enable [testing] in pacman.conf from
releng profile and edit build.sh then add "-s sfs" in make_prepare()

Look at:
    setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -D "${install_dir}" prepare
Replace with:
    setarch ${arch} mkarchiso ${verbose} -w "${work_dir}" -s sfs -D "${install_dir}" prepare

The build requires just half of space that the build for dm-snapshot,
since there is no ext4 img ;)

Just to remember: there is no space gain in .sfs (just about 2M)

There is at least one thing during boot with machine-id service:

f5b84dad94 archiso_pxe_http: Fix location of airootfs.md5
Currently, when booting via HTTP, the airootfs.md5 file is downloaded to
/run/archiso/bootmnt/arch/. However, the checksum file is later assumed
to be located at "/run/archiso/bootmnt/arch/${arch}". Fix the _curl_get
invocation and directly place the file in the right directory.

Fixes a regression introduced in commit b3e1d31 ([archiso] Rework
checksum function, 2014-06-28).

1746e31049 [archiso] Introduce cowfile_size= bootparam
If not set, nothing is changed in current behaviour.

Since dm-snapshot allows to use as "COW" a file with any size,
without caring about the the size of "origin", we can avoid creating a
"COW" file of the same size as the "origin". This is really useful,
when using as cow_device= a filesystem that is VFAT where sparse files
are not supported, so if root-image.fs is 1000M, passing cowfile_size=25%
will create a root-image.cow of 250M instead of 1000M.
