So you want to have vboxadd-service and vboxadd systemd services not starting on Linux kernel versions 4.15 and above? You can manage this by creating a template systemd unit /etc/systemd/system/kernel-version-less-then@.service ----------------------------------- [Unit] Description=Check if currently installed kernel version is less than target [Service] Type=oneshot ExecStart=/usr/bin/sh -c '[[ "$(/usr/bin/vercmp %i %v)" = "1" ]]' Restart=no CollectMode=inactive-or-failed [Install] WantedBy=multi-user.target Then create the directories /etc/systemd/system/vboxadd.service.d/ /etc/systemd/system/vboxadd-service.service.d/ Then for each service /etc/systemd/system/vboxadd.service.d/kerver.conf ------------------------------------------------- [Unit] After=kernel-version-less-then@4.15.service Requires=kernel-version-less-then@4.15.service /etc/systemd/system/vboxadd-service.service.d/kerver.conf --------------------------------------------------------- [Unit] After=kernel-version-less-then@4.15.service Requires=kernel-version-less-then@4.15.service In this way, if my bash-fu is correct, the version compare will fail the kernel-version-less-then@4.15.service and vboxadd and vboxadd-service will not start Giacomo Longo
