It is +a small binary built from systemd source code, but works separately, +similarly to eudev or elogind. It is known to work on both glibc and +musl systems. + +Note that systemd-tmpfiles is specifically for non-systemd systems. It +is intended to be used on an OpenRC system. + +If you wish to selectively test systemd-tmpfiles, follow those steps: + + 1. # emerge --oneshot sys-apps/systemd-tmpfiles + 2. # reboot + +No other steps required. + +If, after reviewing the linked bug reference for opentmpfiles, you feel +your system is not vulnerable/applicable to the attack described, you +can unmask[4] opentmpfiles at your own risk: + +1.
