Calling tune2fs for ext4 partitions at boot costs more than one second boot time on 32-bit Arm systems, with very little gain. Dropping this restores the default periodic fsck *and* saves boot time. Instead of calling sgdisk four times, call it only when resizing and instead use sysfs to find named paritions. Saves seconds on boards with weaker CPU and slow media.

Replace the costly read-only filter loop (awk+tr per line) with a stderr redirect, use /sys/class/net/ instead of ip+jq, and batch all sysctl writes into a single call. Reduces boot time by ~4s on 32-bit Arm systems. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

On single-core Cortex-A7, the YANG bootstrap and config loading is the dominant boot bottleneck. The current sequence spawns three serial phases (bootstrap, sysrepo-plugind, load), each performing independent sr_connect()/sr_disconnect() cycles, and every sysrepoctl/sysrepocfg invocation is a fork+exec that rebuilds SHM from scratch. Replace all three with a single confd binary that does one sr_connect() and performs all datastore operations in-process: - Wipe stale /dev/shm/sr_* for a clean slate - sr_install_factory_config() from the generated JSON - Smart migration: compare config version via libjansson, only fork+exec the migrate script when versions actually differ - Load startup-config (or test-config) via lyd_parse_data() + sr_replace_config(), mirroring what sysrepocfg -I does internally - On failure: revert to factory-default, load failure-config, set login banners (Fail Secure mode) - On first boot: copy factory-default to running, export to file - dlopen plugins and enter event loop The bootstrap shell script is split: config generation (gen-hostname, gen-interfaces, etc.) stays in the new gen-config script, while all sysrepo operations move into the C daemon. The finit boot sequence collapses from 5 stanzas to 2 (gen-config -> confd). Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Simplify and consolidate generation of mdns service records from an external script to C. This reduces fork + exec and saves two seconds of boot time on single core Cortex-A7 systems. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Infix technically does not need to start dbus and dnsmasq before confd has loaded the system startup-config. So we move it in time to save some CPU cycles for confd & C:o. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Also, we don't need to start a logger process for statd, it behaves nicely and uses syslog. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

Allow confd to start even earlier at boot and call 'gen-config' as a background task, pending on it to complete before we load the sysrepo factory datastore. Also, add Finit style progress to console so users can see the phases of the bootstrap process. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Follow-up to 90f619b which first introduced the /etc/hostname.d concept. This commit moves the setup of /etc/hostname.d to post-build.sh dropping the initial call to the hostname activation script a bit, since it is called anyway after bootstrap has finished. The scrip is also given a bit of a refrehs, reducing overhead and needless log messages. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Relocate probe of wifi radios from gen-hardware to 00-probe. This saves one python invocation and some precious CPU cycles at boot. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Neither the Raspberry Pi 2B or the Microchip SAMA7G54-EK board have WiFi hardware by default so drop WiFi, and GPS, support to allow for smaller builds with only the bare essentials in kernel and system. Minimal builds in general don't need WiFi or GPS either, so let's disable them from all. This may become a central theme going forward, keeping the minimal builds ... minimal.

Use SR_SUBSCR_NO_THREAD for all subscriptions and integrate sysrepo event pipes into a libev event loop. This eliminates approximately 30 per-subscription threads, reducing overhead on embedded ARM hardware. A temporary poll-based "event pump" thread handles callback dispatch during bootstrap (where sr_replace_config blocks waiting for callbacks), then exits. After bootstrap, the single-threaded libev loop takes over for steady-state event processing. Note, the confd-test-mode plugin still requires use of threads so we do not create deadlocks when calling sr_replace_config(). Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

Replace logging + logging.handlers with a lightweight syslog wrapper, and argparse with manual argv parsing. On a sama7g54, this cuts yanger startup from ~770ms to ~470ms by eliminating ~300ms of stdlib imports. Also batch external command invocations: - ietf_routing: two sysctl calls instead of two per interface - ietf_hardware: one ls per hwmon device instead of six - bridge: fetch mctl querier data once instead of once per VLAN Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

Description
This PR replaces
sysrepo-plugind+bootstrap+loadscripts with a singleconfddaemon that handles config generation, datastore init, config loading, and plugin management. Uses alibevevent loop withSR_SUBSCR_NO_THREADinstead of ~30 per-subscription sysrepo threads.The new initviz package was used for boot visualization.
Initial work on this branch speed up
sysctl-sync-ip-confandmntscripts, as well as movehostname.dsetup to build-time instead of runtime. To optimize the bootstrap process and free up CPU time on single-core systems, the start of many services have been postponed to either runlevel 2, or afterconfdbootstrap, likedbus,dnsmasq, andstatd. To reduce overhead, we also drop unnecessary logger processes for services that already log to syslog. Even BusyBox has been inspected, we now enable NOEXEC/NOFORK applets.Other interesting changes in this PR is to drop WiFi and GPS from minimal defconfigs. Move WiFi/firmware selects from RPi board
Config.into the full defconfigs so features are explicit rather than implicit via BSP.Checklist
