unix pipes are not devices, so they cannot be mapped by
the device mapper (besides the fact that device mapping
means something completely different ...)

this means that your kernel was built with the device
mapper disabled, but as I said, wouldn't work for pipes
anyway ....

you definitely want to update util-vserver as this version
doesn't work correctly with recent kernels (not that your
kernel is really recent, but recent enough to need a newer
util-vserver)
