Your service should have Before: basic.target After: sysinit.target Then in your service, you can wait as long as you want, while in the background all drivers load. you can do the same as dracut-initqueue. > 4/ reboots or shutdown > NO swaproot and NO os boot > > In the doc, I've been unable to find the following infos: > 1/ how do I tell to dracut to include ALL drivers including frimwares > do I really need to find /lib/modules |xargs to create a full list and give drivers one y one to the dracut command line options? Really no way to specify all drivers or at least all network drivers + all hdisk controler + all filesystems? (for example, the pxeboot image for fedora install has ALL drivers + all firmwares) --no-hostonly for network + disk > 2/ how to I tell to dracut that I don't want swaproot?
