The following commit has removed rpc ports from runqemu-export-rootfs, so
runqemu should also remove them, otherwise "runqemu nfs" doesn't work. And
use
abspath for nfsroot, otherwise it doesn't work when it is a relative path.
That change in question was discussed on list and was supposed to be optional.
Can you confirm that a non-root user can still do a NFS root with both of these
changes applied ?
The runqemu-export-rootfs uses UNFS, no root privilege is required, I can
confirm that both "runqemu slirp nfs" and "runqemu nfs" work well, so I assume
the answer is yes.
