Subject: mtd-utils: add optional systemd service for ubihealthd
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cdf5b47cb640a0a981783d1078625ccacf3b8948;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

mtd-utils: add optional systemd service for ubihealthd

Add support for deploying a ubihealthd.service systemd unit through a
new 'ubihealthd-service' PACKAGECONFIG option.

This change allows systems using systemd to easily enable and manage the
UBI health monitoring daemon as a background service.
