* Add multiple routes support in NetworkManager
Support multiple routes to the same network learned via Router
Information Option. With this change, the kernel will have multiple
routing table entries to a given Thread network. The routes gateway
won't be updated with every new RIO any longer since every gateway
has its own entry.
* Enable IPv6 router reachability probing
Currently router reachability probing is disabled since HAOS enables
IPv6 forwarding and the necessary kernel options are not enabled. With
this change router reachability probing is enabled even though we are
a router on our own.
Note that Linux commit ea659e077528 ("[IPV6] ROUTE: Do not enable router
reachability probing in router mode.") by default disabled this
behavior. But since we are acting as a router as well as a host device,
we rather want this reachability probing.

* Fix swapfile creation for all memory sizes
In certain situation awk prints the swapfile size in scientific
notation. The script can't deal with that, in which case swap file
creation fails.
Use int to convert the number to an integer.
Since pages are 4k, also make sure swapsize is aligned to 4k blocks.
* Add info message
Drop PCIe hotplug since this causes network interfaces name changes
which aren't handled gracefully right now. People are left with no
network configuration.
By default systemd kills the service which causes an OOM. That make
sense for a typical service, however, for SSH we don't want this
behavior: The connection should continue, just the command which caused
OOM should be killed.
* Use zswap instead of swap in zram
This requires a swap file which will get generated automatically on
startup.
* Fix file size and free disk space comparison
* Set zswap factor to 33%
* Set vm.swappiness to 1
Decrease swapping to a minimum. This is also recommended for database
work loads by the MariaDB documentation. In practice it causes the least
amount of writes to disk when under memory pressure, while still making
swap available when needed.
* Avoid moving data to same device
When a data disk move is triggered when the data disk is already in use
the script currently renames that only data disk, rendering the system
unusable.
Don't continue if source and destination happens to be the same device.
* On failure rename to hassos-data-fail
The label hassos-data-failed is too long.
* Deactivate any external data disk device on first boot (#2390)
* Use lsblk to determine the underlying device file
Comparing major number is not reliable, e.g. virtio disks have the same
major number despite being different devices. Use lsblk to find the
underlying device, and compare the device name instead.
By default ConditionFirstBoot is ankered to the presence of
/etc/machine-id. However, in our case /etc/machine-id is a bind mount,
which makes the first boot condition non-working.
Since machine-id is stored by the bootloader on HAOS, use the boot
loaders knowledge and pass the information to systemd.
