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.

Also, ensure the deleted container is actually deleted before recreating
it with a new configuration.

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.

confd: fix missing variable in container script condition
Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
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.

Install the sudo command, and let all members of the "wheel" group run
any command as the superuser.
This ensures that administrators have full access to the system,
primarily for troubleshooting, diagnostics, and remote scripting
purposes.
This adds [PPID] to the syslog lines to the dagger script. After all,
the dagger script is a proxy for confd, so when reading the logs it
seems natural to see the PID of confd rather than a script that will
die soon anyway.

- Relocate python based probe to netconf builds, and
- Restore basic shell script based probe for classic builds
Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
- 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

Move from everything in a single /etc/chrony.conf to a split up with
configuration and server snippets. The latter comes in the form of
configured (static) and DHCP client (dynamic) server setup.
To accomodate this new scheme we need to detect when serves are removed
from the configuration, so not only have the whole change_ntp() been
refactored, it has been extended with a new pass.

The bootstrap script gets feedback from gen-admin-auth, on error we no
longer bail out but instead log the error and continue booting. This
way a developer build with root login can diagnose the error.
When logging the error we also set /etc/issue, /etc/issue.net for local
and remote login services, as well as the dedicated /etc/banner used by
OpenSSH, to hold the error summary. So when attaching to the console
port, or attempting to log in remotely with SSH, the error is printed
to indicate the device is not healthy.
Finally, since factory-config may be missing we need to bootstrap the
sysrepo db with something else, and fortunately we will always have a
failure-config to fall back on.

Break fallback hash to a separate function and allow gen_qemu_system_file()
to return the status. We'd like to update the qeneth templates to include
the same VPD data as is used with qemu.sh, but for now this is sufficient.
The Qemu detection has been changed to the, slightly more, secure detection
of qemu_fw_cfg filesystem.

This commit does several things. Its end goal is to fetch the admin
password hash from VPD memory during factory bootstrap.
To accomplish this probe creates a new file /run/system.json with
information read from a fw_cfg QEMU partition. The data from
/run/system.json is then later used during config bootstrap to fill in
the factory administrator password.
The idea is to make QEMU behave the same way hardware does, i.e. a
default/factory password should be fetched and used from
"hardware memory". The hardware portion of this is yet to be done.

Before this change, the following would happen in /lib/infix/mnt if a
factory-reset was performed:
1. Copy the contents of /var from Squash into /mnt/var and bind mount
/mnt/var over /var
2. Check for factory-reset
3. Clear /mnt/cfg/* and /mnt/var/*
4. Mount overlays
This ordering leaves the system with a completely empty /var on the
boot when a factory-reset is executed. Finit will fixup some of this
via its tmpfiles scripts, but we want the ability to ship files under
/var as part of the Squash and have these be available after the bind
mount, just like what happens at every other boot, when we don't
perform a factory-reset.
We solve this by delaying the bind mount (1) until after the reset has
been performed, together with all the overlays (4). While we're here,
make the fallback case, where no persistent /var is available, use a
bind mount as well. This should allow containers to be tested on such
setups, and it's one less flavor to test.
New order:
1. Check for factory-reset
2. Clear /mnt/cfg/* and /mnt/var/*
3. Mount overlays
4. Copy the contents of /var from Squash into /mnt/var and bind mount
/mnt/var over /var
Now the only difference between a regular boot and a
"factory-reset-boot" is whether (2) executed or not.
Relocate Finit conf to package, like klish and confd. Add condition to
ensure it is not started before mdev/udevd are up and kernel LED modules
have been loaded properly.
Also, add tmpfiles.conf to ensure /run/led is recreated at every boot.

Refactor factory-reset check slightly to check for a Finit condition
from the bootloader, as well as a custom check for br2-externals.
Note, the chgrp call has been extended to ensure admin users have
permission to create any file or directory in any overlay.
