Creating a hidden partition that doesn't mount automatically

I have a drive full of diagnostic images (ASD), and I also use it for storage, installers, etc. When I plug it in to a booted system, it has to mount every single volume (about 25) which can take some time. I would like to keep all the ASD partitions from mounting when plugged in/at boot. I know I can edit fstab on individual machines, but this needs to be a property of the drive, not the computer. It isn't really important to me that the partitions be hidden (not shown in disk utility), but I do need to keep them from mounting.

The OS X recovery partition works in exactly this way, but I don't know how it is implemented. Can someone point me in the right direction?

RUMP_FFS(8)						    BSD System Manager's Manual 					       RUMP_FFS(8)

NAME
rump_ffs -- mount a ffs image with a userspace server SYNOPSIS
file-system PUFFS pseudo-device putter rump_ffs [options] image mountpoint DESCRIPTION
NOTE! This manual page describes features specific to the rump(3) file server. Please see mount_ffs(8) for a full description of the avail- able command line options. The rump_ffs utility can be used to mount ffs file systems. It uses rump(3) and p2k(3) to facilitate running the file system as a server in userspace. As opposed to mount_ffs(8), rump_ffs does not use file system code within the kernel and therefore does not require kernel sup- port except puffs(4). Apart from a minor speed penalty there is no downside with respect to in-kernel code. rump_ffs does not require using vnconfig(8) for mounts from regular files and the file path can be passed directly as the image parameter. In fact, the use of vnconfig(8) is discouraged, since it is unable to properly deal with images on sparse files. In case the image contains multiple partitions, the desired partition must be indicated by appending the token ``%DISKLABEL:p%'' to the image path. The letter ``p'' specifies the partition as obtained via disklabel(8). For example, to mount partition ``e'' from image /tmp/wd0.img, use ``/tmp/wd0.img%DISKLABEL:e%''. It is recommended that untrusted file system images be mounted with rump_ffs instead of mount_ffs(8). Corrupt file system images commonly cause the file system to crash the entire kernel, but with rump_ffs only the userspace server process will dump core. To use rump_ffs via mount(8), the flags -o rump and -t ffs should be given. Similarly, rump_ffs is used instead of mount_ffs(8) if ``rump'' is added to the options field of fstab(5). SEE ALSO
p2k(3), puffs(3), rump(3), mount_ffs(8) HISTORY
The rump_ffs utility first appeared in NetBSD 5.0. BSD
November 21, 2010 BSD
