core: escape unit name from udev
This patch escapes a unit name which was derived from udev.
Please imagine following udev rule.
ACTION=="online|offline", TAG+="systemd", ENV{SYSTEMD_WANTS}="muneda@%p.service"
ACTION=="online|offline", TAG+="systemd", ENV{SYSTEMD_WANTS}="muneda@%r.service"
ACTION=="online|offline", TAG+="systemd", ENV{SYSTEMD_WANTS}="muneda@%S.service"
When unit name is derived from udev via
udev_device_get_property_value(), the name may contains '/' if
ENV{SYSTEMD_WANTS} has the udev options $devpath(%p), $root(%r), or
$sys(%S). However, '/' is a invalid char for unit name so processing
of this rule fails as Invalid argument with following message.
Apr 22 13:21:37 localhost systemd[1]: Failed to load device unit: Invalid argument
Apr 22 13:21:37 localhost systemd[1]: Failed to process udev device event: Invalid argument
This patch escapes those invalid chars in a unit name.
Tested with 202, and confirmed to apply cleanly on top of commit 195f8e36.
Thanks,
Takahiro
