I'm aware that unionfs status and I think it's usable in 7.x, right? I was asking about nullfs because the following lines in sys/conf/NOTES: # NB: The NULL, PORTAL, UMAP and UNION filesystems are known to be # buggy, and WILL panic your system if you attempt to do anything with # them. They are included here as an incentive for some enterprising # soul to sit down and fix them. Regards, Rong-En Fan > > -- > Thanks, > > Josh Paetzel > >
