The other possibility, used by our builder:


-- 8< --
marck at beaver:~> cat /etc/fstab 
tmpfs           /b              tmpfs   rw              0 0

marck at beaver:~> cat tb-tmpfs 
#!/bin/sh

TBHOME=/usr/local/tb

BLIST=`${TBHOME}/scripts/tc listBuilds`

for n in $BLIST; do
        mkdir -p /b/$n
        d=${TBHOME}/$n
        rm -rf $d
        chflags -R 0 $d
        rm -rf $d
        mkdir -p $d
        mount -t nullfs -onoclusterw /b/$n $d
done 
-- 8< --

so even dist tarballs are unpacked to tmpfs

Sometimes I'm still experienced lockups between ZFS and TMPFS though are 
quite rare even if I use 3 or even 4 parallel tinderbuilds.

YMMV, of course...
