Joachim Wiberg d8dde9cde2 confd: add support for custom container ENTRYPOINT
This was a tough nut to crack.  Turns out the trick to changing the
ENTRYPOINT is to set --entrypoint=command and then call 'podman create
... command args'.  Not entirely obvious since the documented approach
is to use a JSON array as the argument: podman create
--entrypoint='["command", "args" ]'.

Admittedly, encoding this in C to transfer it via a POSIX shell script
to the command line, is not the easiest task I've undertaken.  So I gave
up and found this workaround.

Worth noting, however, is that one *must* set `--entrypoint`, it is not
enough to just append the command to the 'podman create' command line.
Due to differences in docker and podman, we cannot supply the full args
to an alternate entrypoint command.  But for the command to actually run
we need to override the image's ENTRYPOINT and send the command and args
as the last arguments on the command line to podman create.

Joachim Wiberg 2b19b61068 confd: add support for manual start of containers
This commit adds 'manual:yes' to the container's Finit service
configuration and changes from pod: to container: prefix for a
unique namespace to prevent collision with regular services.

The prefix container: is more correct that pod:, which should
be reserved for any future pod support.

Joachim WibergandTobias Waldekranz 228891935d dhcp-client: allow setting hostname, and update /etc/hosts
This should be the last outstanding issue to fix #278.  Please note,
it is undefined what happens if you have two DHCP clients that request
hostname, and changing hostname from NETCONF at runtime will overwrite
any hostname set by the DHCP client.

Joachim WibergandMattias Walström 2fa5dcfea0 board/common: major refactor of udhcpc script
- New log() function replaces stdout logging
 - New set_dhcp_routes() and clr_dhcp_routes() functions
   - Set all option 121 routes with same metric
   - Set all option 3 routers with increasing metric (this is what the
     reference udhcpc scripts do, and RFC says the routers should be
     listed in order of preference ...)
   - Clearing routes must, like IP addresses, be done both by interface
     and protocol.  This refactor makes sure to delete any DHCP routes
     set on the given interface (in case options change)
 - Use resolvconf per-interface search+nameserver
 - Cache IP lease so we can ask for it back later
 - On deconfig|leasefail|nak, make sure to clean up anything that might
   be lingering from this interface.  E.g., we can get leasefail when a
   server denies our request to prolong a lease.
 - On renew|bound, refresh routes, and set search+dns + NTP servers

Richard AlpeandJoachim Wiberg f75053c931 udhcpc: convert default.script to use ip not ifconfig
This fixes one bug in Infix, namely that dhcp removes all other
statically configured addresses. However it introduces a new one
where dhcp renewals with new ip addresses are added as "duplicates",
we fix this in a later commit in this patchset.

Joachim WibergandTobias Waldekranz 17ff8677ee board/common: replace default editor, nano -> mg
This reverts an earlier change where nano was made the default editor in
a misguided attemt by yours truly to accomodate beginner users.

With the recent improvements of the CLI and the fact that the NETCONF
support has matured greatly, the need for a user-friendly editor have
diminished drastically.  Editing system files is now limited to devs
and the core team prefers Mg over nano and vi.

Joachim Wiberg 4ca58836b4 board/common: replace edit and editor with symlink to nano
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.
