Subject: fix reload propagation for device alias
X-Git-Tag: v237~59
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=bf70ff2cff719905f9dc3f726eaba79780dcae55;p=thirdparty%2Fsystemd.git

fix reload propagation for device alias

udev-made .device aliases are not normal alias

They are full-fledged units which are linked to
the same sysfs path

we need to explicitely propagate reload to all
alias
