* Default Dracut
Dracut without any parameters should generate an initrd image capable of
booting a generic machine. 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.
The default dracut image could be delivered as an rpm along with the kernel.
Configuration files could be injected via "gunzip|cpio -A|gzip", though
modifying the md5 hash sum.
* --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?
yes
* (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
use dracutmodules=""
- certificates or passwords for iscsi or kerberized nfs
inject configuration files in the standard "Default Dracut" image via
"gunzip|cpio -A|gzip"
How should this mode be specified from the command line?
