I've committed the removal of -x cpio, mostly to record the problem.
Please try the following patch. Since we're already using /rescue, we
might as well use tar which is way more capable than pax.

Setting up a FreeBSD diskless client with read-only root filesystem is not working if one is using /conf/base/etc.cpio.gz as /etc base. The first problem is the use of the pax(1) command to extract the etc.cpio.gz file into the mfs for /etc. pax(1) is bailing out with > pax: Invalid combination of options: -f -p -r -x If the "-x cpio" option is removed pax(1) is working correctly and is determining the archive type automatically. The next problem is related to pax(1) too but only happens with a read-only /tmp via NFS. pax(1) tries to create a temporary file to store directory times in /tmp. If /tmp comes read-only (together with / via NFS) pax(1) is bailing out again. Unfortunately, it is not possible to create an mfs based /tmp without hacking rc.initdiskless as mounting filesystems from /etc/fstab or creating an mfs based /tmp via /etc/rc.d/tmp is done later. The same applies to FreeBSD-5.4 and /etc/rc.d/initdiskless. Fix: The first problem can be fixed by removing "-x cpio" from the pax(1) invocation line in rc.initdiskless. The second problem can be fixed by forcing the execution of "/etc/rc.d/tmp start" in /etc/rc before rc.initdiskless is started. How-To-Repeat: Follow the instructions for diskless(8) to setup the whole thing. Generate an appropriate /conf/base/etc.cpio.gz from your distribution /etc dir. PXEboot the client and wait for rc.initdiskless to kick in.
