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.

The name is more relevant since the usage is shared for both
dm-snapshot and overlayfs.

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:

Copying big amount of data results in bad performance as data is
written in chunks of 4kiB (8 * 512 bytes).
The default is not changed but can be overwritten.

Remove unused feature, just to save space
sizeof ext4 image (empty): 4.3M vs 403K (du airootfs.img)
sizeof used space (empty): 48M vs 20K (df)
Thanks Christian Hesse for initial tip.

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).

Among other things, 36459f3 ([archiso] Drop aitab support, 2014-06-28)
removed the possibility to manually set a specific architecture by using
kernel parameters. This, however, is useful, e.g. when installing Arch
Linux on a device that reports itself as i586 but works fine with the
i686 flavor.

* Make it ISO9660 friendly (extra dot "." is replaced by "_")
* Was used when support both .fs.sfs and .sfs
|

Always create one filesystem of a fixed size (32G), format (ext4) and
know name "airootfs".
Simplify logic a lot.
|
|
|
|
There is no big overhead.
Space usage in ext4-1G is ~0.4M while in ext4-32G is ~4M.
Just use a big value to make all people happy.

Two purposes:
* systemd filename friendly: "-" is used for "/" and must be escaped with "\x20"
* ISO9660 filename friendly: "-" is replaced with "_"

Ensure that all inode table is initialized at filesystem creation.
(Anyway filesystem is small, so at first mount is may quickly initialized)
This avoid possible COW usage during runtime ;)

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.

This reverts commit 6f68bec907f5fbfdd1e73be8812ea0ff925965aa.
Using ash was actually correct as only this shell is available in initramfs.
It was the commit message of 27940c420f01f550f36c3aa25633b43a4f2a2069 that was wrong
