Keep the transient files in the system's /mnt/tmp, and only persist
startup_db in /cfg.
This design (with a symlink) means that /cfg/startup_db _must_ exist
in order for clixon to start properly. Therefore run
/lib/infix/prep-db to take care of this.
At the moment, this just creates an empty factory config, and copies
it to startup if it doesn't exist. In the future, prep-db could select
a factory config based on some hardware identifier, or even build one
dynamically, based on available ports etc.
This reverts commit 2ddf9448fe.
Two reasons:
1. We will move to a debian-style /etc/ssh/ssh_config.d/ structure
soon.
2. In a managed scenario, NETCONF could be disabled, so mech should be
responsible for activating it at boot.
The allows remote NETCONF access to the Clixon example (for now). This
will be replaced later with the Clixon Infix system.

In the new model, we have three sources of storage:
- /mnt/var: Mountpoint for a disk with the label "var"
- /mnt/cfg: Mountpoint for a disk with the label "cfg"
- /mnt/tmp: Mountpoint for a ramdisk
These sources are used for the following overlays:
- **/cfg, /home, /root**: /mnt/cfg if available, else /mnt/tmp
- **/etc**: /mnt/cfg if available and the boot/etc finit condition is
set, else /mnt/tmp
- **/var**: /mnt/var if available, else /mnt/tmp
- **/var/lib**: /mnt/var if available, else /mnt/cfg if available,
else /mnt/tmp
See board/common/rootfs/lib/infix/mnt for more information.
The nano editor has been shown, over and over again, to be more
user-friendly to complete UNIX/Linux beginners than even Mg.
Also, change the default pager/less to be less (again), it was
very confusing to have less be most and more just be more. We
recommend scripts to use pager and edit/editor to call system
safe defaults.

Regrettably, the latest additions of functionality to Infix have also
incresed the size of the ramdisk. We expect it to go down slightly
before v1.0, but considering we'll add Frr before then it's better to
be realistic of our needs when run in GNS3.

- Replace ISC dhclient with dhcpcd => IPv4 link-local address
- Enable openresolv to handle /etc/resolv.conf for us
- iproute2 was a dependency of ifupdown2, but now we need to
enable it explicitly
- Ensure we have the same default system interface in infix
- Reenable BusyBox applets disabled when enabling ifupdown2, for
infix derivatives that may prefer a smaller base image.
Note: ifupdown-ng prefers dhcpcd over udhcpc, so no risk for conflict by
reenabling udhcpc.

This change adds a `factory` tool, and login shell, that schedules a
reset of all writable (overlay) filesystems. The tool is set up with
the suid gid flag to allow all members of the wheel group to perform
the reset.
The login method only allows reset from /dev/console, to prevent any
malicious reset over SSH. This should be further constrained later
when PAM is introduced.
To initiate factory reset from the login prompt, use login/pass:
factory/reset
To initiate factory reset from the shell, call
factory
Both methods are interactive by default, but two command line options
can be used to modify the behavior:
-r Skip reboot, and "reboot now?" question
-y Assume yes to all questions, for non-interactive use

This change checks¹ if the system does not have a br0 interface, creates
a default one consisting of all switch ports in VLAN 1 of br0.
On top of br0 a vlan1 management interface is created with DHCP address.
For emulation and test purposes, a way to supply tap interfaces from
Qemu, and pass off as if they were regular switch ports, is added.
____
¹ obviously a better way to detect a factory-reset device is needed,
not all systems running infix will need or want a br0 interface.
