Pull request overview
This PR upstreams an existing patch to set SyslogIdentifier in multiple systemd unit files so that logs emitted by services started via /bin/sh -c ... show a meaningful identifier instead of sh in journalctl.
Changes:
- Add
SyslogIdentifier=...to key CCSP/RDK service unit files to improve journal/syslog attribution. - Standardize log identifiers per service to reduce ambiguity when multiple components log concurrently.

A previous changeset made all services invoked via the "/bin/sh -c '(...)'" pattern, which causes all syslog/journalctl entries to have the "sh" process name. This can cause a lot of confusion when viewing the system log via journalctl: rdkb-arm sh[5613]: Fetching values to form parodus command line arguments rdkb-arm sh[5151]: result = rdkb-arm sh[5151]: result = rdkb-generic-broadband-image_rdkb-2025q1-kirkstone_20250606001224 rdkb-arm sh[5613]: Framing command for parodus rdkb-arm sh[5613]: Starting parodus with the following arguments rdkb-arm sh[5613]: ModelName=RPI SerialNumber= Manufacturer=Traverse HW_MAC=00:0a:fa:24:29:5d ... rdkb-arm sh[5808]: rdk_dyn_log_initg_dl_socket = 3 __progname = parodus rdkb-arm sh[5551]: Conf file /etc/debug.ini open success rdkb-arm sh[5551]: rdk_dyn_log_initg_dl_socket = 3 __progname = CcspTandDSsp rdkb-arm sh[5551]: rdk_logger_init /etc/debug.ini Already Stack Level Logging processed... not processing again. rdkb-arm sh[5551]: ****LOADING DM LIBRARY*************** rdkb-arm sh[5573]: CosaEthInferface initialization done! rdkb-arm sh[5573]: CcspHalExtSw_getAssociatedDevice not implemented on generic arm platforms yet In the above output there is a mix of CcspPandMSsp, Parodus and CcspEthAgent, which is very confusing.

RDKBACCL-1777 : Set systemd 'SyslogIdentifier' parameter
Reason for change: syslog / journal entries in systemd log can no longer be differentiated between services
Test Procedure: Build RDK image and verify output with
journalctl -f(see details below), the process name should match the originating service (like CcspPandM, CcspEthAgent) and NOTshRisks: Low
Priority: P2
This patch has been part of meta-rdk-bsp-arm for a while and I believe it would be beneficial to upstream it.

edited to add (2026-07-16): while there are many other service files in the
systemd_unitsfolder, we have only modified the ones we are sure we are using
