This setting allows services to run in an ephemeral copy of the root directory or root image. To make sure the ephemeral copies are always cleaned up, we add a tmpfiles snippet to unconditionally clean up /var/lib/systemd/ephemeral. To prevent in use ephemeral copies from being cleaned up by tmpfiles, we use the newly added COPY_LOCK_BSD and BTRFS_SNAPSHOT_LOCK_BSD flags to take a BSD lock on the ephemeral copies which instruct tmpfiles to not touch those ephemeral copies as long as the BSD lock is held. |

Files in this directory contain configuration for systemd-tmpfiles, a program to create, delete, and clean up volatile and temporary files and directories. See man:tmpfiles.d(5) for explanation of the configuration file format, and man:systemd-tmpfiles(8) for a description of when and how this configuration is applied. Use 'systemd-analyze cat-config tmpfiles.d' to display the effective config.
