Just use chmod +t /usr/tlaronde/rodata in order to avoid archiving your read-only data on venti. The same is true about /tmp. Actually ls -l /usr/tlaronde/tmp will show you that /tmp has already the +t bit. However, yes you can also use ramfs if you have enough RAM. :-) IMHO, the default layout is good enough for your needs. -- Vivien
