The e2scrub utilities only make sense on system which use LVM. They
come with e2fsprogs and can't be disabled currently. Drop them manually
in our post-build script.
* Add development build version part to version number
Add third part in the version number to indicate development builds.
Generate a default version number based on the date, e.g.
"5.6.dev20201124".
* Add GitHub Action workflow for development builds
Add another GitHub workflow for development builds. Make it triggered
only for now. The version number is generated by the workflow and
passed to all builds to make sure all builds have the same development
build version.
* Add documentation
* Add resolved.conf to disable stub resolver and DNSSEC
There are Add-Ons which try to bind port 53 on all interfaces including
127.0.0.53. Disable the stub resolver to make them continue working. We
don't need the resolver currently anyway.
Also disable DNSSEC to make sure the baords can access a NTP time server
even when their time is incorrect (since DNSSEC validation may fail).
This is a known chicken-egg problem with systemd-resolved/systemd-timesyncd
and might be addressed in a future version, with what we can reenable
DNSSEC:

* Make sure resolve gets added only once to nsswitch.conf
Only add resolve to nsswitch.conf if not already present.
* Update buildroot-patches for 2020.11-rc1 buildroot
* Update buildroot to 2020.11-rc1

* Don't rely on sfdisk --list-free output
The --list-free (-F) argument does not allow machine readable mode. And
it seems that the output format changes over time (different spacing,
using size postfixes instead of raw blocks).
Use sfdisk json output and calculate free partition space ourselfs. This
works for 2.35 and 2.36 and is more robust since we rely on output which
is meant for scripts to parse.
* Migrate defconfigs for Buildroot 2020.11-rc1
In particular, rename BR2_TARGET_UBOOT_BOOT_SCRIPT(_SOURCE) to
BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT(_SOURCE).
* Rebase/remove systemd patches for systemd 246
* Drop apparmor/libapparmor from buildroot-external
* hassos-persists: use /run as directory for lockfiles
The U-Boot tools use /var/lock by default which is not created any more
by systemd by default (it is under tmpfiles legacy.conf, which we no
longer install).
* Disable systemd-update-done.service
The service is not suited for pure read-only systems. In particular the
service needs to be able to write a file in /etc and /var. Remove the
service. Note: This is a static service and cannot be removed using
systemd-preset.
* Disable apparmor.service for now
The service loads all default profiles. Some might actually cause
problems. E.g. the profile for ping seems not to match our setup for
/etc/resolv.conf:
[85503.634653] audit: type=1400 audit(1605286002.684:236): apparmor="DENIED" operation="open" profile="ping" name="/run/resolv.conf" pid=27585 comm="ping" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
Drop AVAHI and use systemd-resolved to announce hostname via mDNS
and LLMNR. Also continue to offer the _workstation._tcp.local service
since it is used by the CoreDNS mDNS plug-in.
Currently the Microsoft Reserved Partition GUID is used for this FAT32
formatted partition. This GUID is a rather Microsoft Windows specific
GUID and not commonly used on Linux.
On Linux systems partitions of this type do not get automatically
mounted (see /usr/lib/udev/rules.d/80-udisks2.rules). However, since
this partition contains some files user commonly need to adjust
(config.txt, cmdline.txt) it would be good if the partition does get
mounted.
Use Microsoft Basic Data instead, which is used by default for FAT32
partition (even by Linux partitioning tools such as gparted). Tested
on ASUS Tinker Board and RPi4.
Aligning partitions (and hence file system structures) to higher level
then 512 byte sectors is common practise and highly recommended for flash
backed block devices. It makes sure that the underlaying flash translation
layer (FTL) does not amplify writes due to missalignment of its erase
block size. Use a 1MiB boundary which is what a modern fdisk is doing.
