So this might not have been clear earlier, but stating it on the list to
be sure everyone is on the same page.
* 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.
* --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?
