Instead of having to scroll to the end (Shift G, or page down til end), let's instead start at the end now that we have control over paging in the CLI ourselves. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
The -S switch to less seemed at the time a good idea -- chop off too long lines and allow horizontal scrolling -- however, the -F option, to skip pager for content that fit the first screen is overridden by the -S switch. This makes commands like "show containers", and similar that normally have waaaaay too few lines for a pager to always page. So let's drop -S to regain the original behavior. This will cause lines to be wrapped, but with the new raw mode in the CLI this seems to work without any weird screen artifacts. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
The mDNS daemon, Avahi, is very verbose in its syslog output. So much that it often overshadows other subsystems, and on switches and routers with more than the "normal" amount of ports and interfaces, it quickly becomes unbearable. The patches consist of: - Add -l LEVEL support to avahi-daemon - Add missing casll to setlogmask() in libdaemon:daemon_set_verbosity() Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
When deleting interfaces we skip a lot of steps in netdag_gen_iface(), this patch ensures we at least call netdag_gen_ipv4_autoconf() to drop any running zeroconf agent in the same generation. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

All hail @troglobit - destroyer of complexity! 😆
Just want to check the "no enable" behavior before approving.
This is a complete redesign of how the system creates/deletes containers from the running-config. Containers are now removed synchronously from confd before any interfaces they may be using are removed, and created in parallel, using a Finit task, well after confd has finished setting up interfaces. The logic previously provided by execd to retry container create on any route/address changes, or periodically every 60 seconds, is now handled by a new 'setup' command in the container wrapper script. Additionally, container create is now split in wget/curl/podman pull of the image and 'podman create'. This to both consolidate image fetching and improve user feedback since most of the retry logic (above) revolves around the image download.

Since `conmon` only logs the output from the monitored container's `stdout`/`stderr`, we might as well get rid of `k8s-logger`, and let the output pass through to finit, which will then pipe the messages to syslog. Fix #836
When disabling a container in the configuration we should not remove it, because then any volumes used by it may be lost. Instead, we now simply disable the service to prevent it from starting, or stopping it, if it was running. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
