This is my 4000/60 with an emulated 2 GB root disk and another 16 GB (also a PiSCSI emulated disk) for /usr/src: # df -h Filesystem Size Used Avail %Cap Mounted on /dev/sd0a 1.7G 1.3G 337M 80% / kernfs 1.0K 1.0K 0B 100% /kern ptyfs 1.0K 1.0K 0B 100% /dev/pts procfs 4.0K 4.0K 0B 100% /proc tmpfs 20M 4.0K 20M 0% /var/shm /dev/sd1c 15G 11G 3.7G 74% /usr/src # swapctl -l Device 1K-blocks Used Avail Capacity Priority /dev/sd0b 16384 6256 10128 38% 0 _swapfile_ 716800 2028 714772 0% 1 Total 733184 8284 724900 1% I kind of forgot to have a reasonable amount of swap (as that host only has 80 MB RAM), so I placed some swapfile. Not the most performant option, but it worked successfully. This setup (~ 16 GB for sources, 2 GB for the system, ~ 700 MB swap along with 80 MB of real RAM) was successfully able to produce a working ISO install image (which I also tested successfully.) Details about my build approach are in my most recent emails. If you go for a 512 MB SIMH VAX, things may be quite faster (esp. on a fast host) than with my real hardware VAX. With the most modern, top-of-the-line hardware, I guess I would be a matter of a few days only. MfG, JBG --
