The cfg.ext4 disk image was created but not formatted because mkfs.ext4
wasn't found. As sbin is not in PATH for an unprivileged user in
Debian.
This caused the VM boot to fail with "No persistent storage found for /cfg".

Attempt to fix permissions with sudo before falling back to $HOME,
and verify directory is actually writable before proceeding.

Actually disable iitod on Styx DCP-SC-28p to work around #670, this
prohibits software control of LEDs, leaving the default HW control,
which has proven more stable on this platform.

This update got pretty messy, since libyang had some
breaking changes. And unfortunatly rousette, libyang-cpp
and sysrepo-cpp has not made any new release yet.
We previously run a draft version of a lot of YANG models,
netconf-server,ssh-server and mode. Now they are released
with minor changes.
infix-meta is an exception, here we had to remove the obsolete
marker of the node and value, since this is no longer allowed in
libyang.
Previously rousette did not install the yang models so we kept a copy
of them in confd. Now it is implemented in rousette, let them install
their models.
On platforms based on CN913{0,1,2}, collect all ECC related counters
so that we know if any correctable errors have been encountered since
the most recent boot.
Allow particular boards or platforms install hardware specific scripts
in /etc/support.d, via the usual /usr/share/product logic, which are
then run by /sbin/support and included in the resulting bundle.
This lets us collect hardware specific information, e.g., SoC-specific
error counters, without /sbin/support needing to know about all the
nitty gritty details.
Verify that if the system encounters a hard lockup, i.e., interrupts
are no longer being serviced, then the system's watchdog will
correctly reboot it.
Rev. A has a FLASH that Linux reconfigures to 4B-addressing, but must
be in 3B-addressing when accessed by the BootROM. Since it has no
reset input, this would not work on warm resets. Linux has a
workaround for this issue for the common case of a controlled reboot,
which this change enables on those boards (which are admittedly few
and far between, but still useful as testing vehicles).
(This won't take effect until Finit is updated to at least 4.15, which
switches over from watchdog- to reboot(2)- based reboot, by default)
By default, ensure that the target device accepts TCP connections on
the specified port before returning the device object. This aligns the
SSH implementation with {NET,REST}CONF.
This solves the issue where tests that use SSH commands early in their
execution would sometimes fail as the remote server had not started up
yet.
Store historical snapshots as compressed .json.gz files to reduce disk
usage. The operational.json file remains uncompressed for easy access.

Dump operational datastore to timestamped JSON snapshots every 5 minutes
(in /var/lib/statd/). The operational.json symlink always points to the
latest snapshot.
Implement hierarchical retention policy that keeps the first snapshot of
each time period (hour/day/week/month/year), providing fine-grained recent
history while preventing unbounded disk usage.
This will allow us to plot / track how the system state evolves as
well as give us somewhat fine-grained info in the case of an event,
such as a crash.
Add unit test simulating months of snapshots to verify retention
behavior using a statd stub that only runs the retention code locally
(unit test)

Turn on OOPS-to-panic, soft/hard lockup panic, hung-task panic, and
extra workqueue watchdog reporting. This makes latent stalls visible
instead of silently freezing, improving diagnosis of issues like the
recent resource-pressure lockup.
