platform: use also statvfs() to check for udevd (!639) · Merge requests · NetworkManager / NetworkManager

Alfonso Sanchez-Beato requested to merge alfonsosanchezbeato/NetworkManager:improve-udevd-detection into master Oct 05, 2020

Check whether or not there is a running udevd by using statvfs() on "/sys" and use access() as a fallback. This is in line with what is done by systemd [1] and helps in case NM is not really running in a container but has been confined by a MAC so it does not have full access to sysfs (access() returns EACCES). This fixes https://bugs.launchpad.net/snappy-hwe-snaps/+bug/1712918
