During post-migration testing you discover that the server fails to boot because the initramfs image for the current kernel is missing the qla2xxx Fibre Channel driver. You have booted the system from rescue media, chrooted into /mnt/sysroot, and need to rebuild the initramfs inside the chroot environment. Your goals are:
Rebuild the initramfs for the currently running kernel version inside the chroot
Overwrite the existing image
Add the qla2xxx kernel module in addition to the modules that dracut normally selects
Leave the standard driver-loading sequence unchanged
Which dracut command meets all of these requirements?
The --add-drivers option tells dracut to add one or more kernel modules in addition to its normal hardware detection, while -f (or --force) overwrites the existing initramfs image. Calling dracut without an explicit image or kernel version when running inside the chroot automatically operates on the current kernel and the default file in /boot.
dracut -f --add-drivers "qla2xxx" satisfies every requirement: it overwrites the image, targets the running kernel, and appends the qla2xxx driver without excluding other modules or changing the normal load order.
--drivers would create an image containing only the listed drivers, dropping everything else-contradicting the requirement not to exclude modules.
--force-drivers also adds the driver but forces it to load early and, combined with --hostonly, further limits included modules; both behaviors violate the stated constraints.
--add works only for dracut modules, not kernel drivers, so it would not include the qla2xxx driver at all.
Therefore the first command is the correct choice.
