Both solutions will work. For Fedora >= 19, it's even simpler. Just add the option "x-initrd.mount" to the /boot /etc/fstab entry. The /usr/lib/systemd/system-generators/systemd-fstab-generator takes care of generating a mount unit, after root is mounted. systemd mounts it as part of initrd-fs.target. See man dracut.bootup(7). You can put your custom service in initrd.target.wants with: After: initrd-fs.target Before: initrd-cleanup.service /boot is mounted at that point of time. -- To unsubscribe from this list: send the line "unsubscribe initramfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
