--kerneldir option should only be about where to get kernel modules from, not about where to place them inside initramfs. But the actual result is that modules are copied preserving the full path, effectively making the modules "missing" in the initramfs (because are placed outside of /lib/modules).

Example test case:

$ dracut --nomdadmconf --nolvmconf --kmoddir ~/install-mod/lib/modules/4.4.38-11.pvops.qubes.x86_64 --modules 'kernel-modules qubes-vm-simple' --conf '/dev/null' --confdir '/var/empty' -d 'xenblk xen-blkfront cdrom ext4 jbd2 crc16 dm_snapshot' -f initrd.test 4.4.38-11.pvops.qubes.x86_64
$ lsinitrd initrd.test |grep /lib/modules
Arguments: --nomdadmconf --nolvmconf --kmoddir '/home/user/install-mod/lib/modules/4.4.38-11.pvops.qubes.x86_64' --modules 'kernel-modules qubes-vm-simple' --conf '/dev/null' --confdir '/var/empty' -d 'xenblk xen-blkfront cdrom ext4 jbd2 crc16 dm_snapshot' -f

dracut-install: install kernel modules to /lib/modules/$kernelversion
be5025b 
Specifying a different kernel module directory with --kmoddir would
result in the same directory being the destination directory.

Strip everything before the "/lib/modules" for the destination dir.

@marmarek
Workaround for buggy dracut in Fedora 25
0923b40 
dracut --kmoddir is broken in dracut-044 (mangles module path inside
initramfs). This is already fixed upstream, but updated package still
haven't been uploaded to Fedora 25.
For now, postprocess the initramfs fixing the path.
