It didn't apply for me; I manually edited the file and rebuilt
ramdisk-zfsroot.fs, replacing the previous version. It didn't seem to
make any difference, I still can't modload anything, even if the paths
after the pivot appear correct:

#  / sysctl kern.module.path
kern.module.path = /stand/amd64/9.99.47/modules
#  / ls /stand/amd64/9.99.47/modules/vboxguest
vboxguest.kmod
# / modload vboxguest
modload: vboxguest: No such file or directory

Swap also can't be added.
