This reverts commit 4fa9aaf0be.
That seemed like a good idea allowing us to include any runtime
generated file in archive. Unfortuantely it broke backups with files
from mounted directories.
When mounting overlay with / as lowerdir its mounts don't propagete in
the mountpoint. That resulted in empty directories:
/tmp/overlay.XXXXXX/backup/tmp/
/tmp/overlay.XXXXXX/backup/var/
/tmp/overlay.XXXXXX/backup/dev/
/tmp/overlay.XXXXXX/backup/proc/
etc.
As some platforms / users try to backup files like /var/dhcp.leases or
/boot/cmdline.txt it means we can't use that solution.

Disabled services should be kept disabled after sysupgrade. This can be
easily handled using a proper uci-defaults script.
Extend sysupgrade to check for disabled services, generate uci-defaults
script disabling them and include it in backup.

Setting overlay while creating backup allows including extra files in
archive without actually writing them to flash. Right now this feature
is limited to /etc/backup/ directory and is used only for including
installed_packages.txt.
Extend this solution to make it more generic:
1. Always mount overlay while creating backup
2. Overlay whole / to don't limit it to /etc/backup/
This allows including any additional files in backups and adding more
sysupgrade features.

When tar was failing, it was exiting immediately. Some files and the
tmpfs mount (-k) would remain breaking the next backup attempt.
Also remove redundant $? from exit builtin call as exit already returns
the last command exit code when called.

tar stderr was probably discarded only to remove this message:
tar: removing leading '/' from member names
However, together with that, any other error would also be discarded.
It is easier to fix that allowing the error message to be printed.
In sysupgrade, the backup file list only uses absolute paths. That way,
the solution is to remove the leading '/' from all files (sed) and chdir
to / (option -C /)

Downstream projects might re-generate device-specific configuration
based on OpenWrt's defaults on each upgrade, thus being unaffected by
forward- as well as backwards-breaking configuration.
Add a new sysupgrade parameter, which allows sysupgrades between minor

versions.

Commit "initramfs: switch to tmpfs to fix ujail" switched initramfs to
now use tmpfs, it causes $(rootfs_type) to now return tmpfs when
running initramfs image instead of being empty.
This broke initramfs detection which prevents config files from
being saved as it does not work from initramfs.
So, lets test for $(rootfs_type) returning "tmpfs" instead.

With package "coreutil-sha256sum" installed "sysupgrade" fails to perform 'sha256sum -s' and instead returns 'invalid option -- 's''.
This is caused due to:
different syntax for a sha256sum status check ('sha256sum --status' with "coreutil-sha256sum")
'/usr/bin/sha256sum' being symlinked to '/usr/bin/gnu-sha256sum' (after installation of "coreutil-sha256sum")
"coreutil-sha256sum" package from the packages feed replaces the Busybox sha256sum
This patch restores for 'sysupgrade' the busybox call to its sha256sum applet.

So far firmware validation result was binary limited: it was either
successful or not. That meant various limitations, e.g.:
1) Lack of proper feedback on validation problems
2) No way of marking firmware as totally broken (impossible to install)
This change introduces JSON for storing detailed validation info. It
provides a list of performed validation tests and their results. It
allows marking firmware as non-forceable (broken image that can't be
even forced to install).
Example:
{
"tests": {
"fwtool_signature": true,
"fwtool_device_match": true
},
"valid": true,
"forceable": true
}
Implementation is based on *internal* check_image bash script that:
1) Uses existing validation functions
2) Provides helpers for setting extra validation info
This allows e.g. platform_check_image() to call notify_check_broken()
when needed & prevent user from bricking a device.
Right now the new JSON info is used by /sbin/sysupgrade only. It still
doesn't make use of "forceable" as that is planned for later
development.
Further plans for this feature are:
1) Expose firmware validation using some new ubus method
2) Move validation step from /sbin/sysupgrade into "sysupgrade" ubus
method so:
a) It's possible to safely sysupgrade using ubus only
b) /sbin/sysupgrade can be more like just a CLI

Some functions only used by stage2 are moved there from common.sh.
One piece that could still use more cleanup is platform_pre_upgrade: many
targets reference files from there are aren't available in the ramfs, so
we need to evaluate it before the switch; conversely, flash writes happen
in that function on some targets. Targets that do the latter should be
fixed eventually to use platform_do_upgrade for that purpose.

With this patch sysupgrade will write directly to the partitions
instead of to the main disk. The UUID is copied from the image
to the MBR as well. This prevents the mbr from being completely
overwritten and losing the partition table. The -p option has
been added to maintain the original behavior and overwite the
entire disk with the new image. Tests have been added to ensure
that the image partitions match up with the active partitions.

Current NAND sysupgrade process is a bit hard to follow due to the way
of triggering stage1. Currently this is done by leaving a /mark/ in the
form of /tmp/sysupgrade-nand-path during nand_do_platform_check.
Existence of this mark stops standard sysupgrade process (as the result
of sysupgrade_pre_upgrade exit). This may be a bit misleading.
Proposed solution adds a new function that will allow platform.sh
trigger NAND sysupgrade consciously. This will also allow cleaning
nand_do_platform_check limiting it to just checking the image.
