SUMMARY = "Systemd service masking for container use"
DESCRIPTION = "Masks systemd services that are inappropriate inside containers \
    (udev, hwdb, serial-getty, etc.). Installed as a package so it works \
    with both single-layer and multi-layer OCI images."
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
