This means it must not detect anything of the current running system to determine what to install in the image. This includes stuff in /proc, /sys, lsmod, /proc/mounts and possibly more. By necessity, stuff in the filesystem are usable to dracut in determining what to install in the image. * --hostonly mode Host only mode is permitted to use runtime detection to generate an image capable of booting the current system. What exactly does this mean? Is this primarily for smaller sizes by avoiding irrelevant modules? * (Some other generation mode) Perhaps we need more generation modes for other purposes. One likely case is where you need to generate a machine specific image for a non-local system. A combination of command line options and/or .conf file would define the dracut image for a non-local system. This might be necessary for cases like: - netboot initrd needs to be as small as possible for resource constraint reasons - embedded systems with resource constraints - certificates or passwords for iscsi or kerberized nfs How should this mode be specified from the command line?
