Sure. It might also be a good idea to ask portmgr@ to grep tarballs for rlim_t so we can inspect source code. I just realized that there is a potential for non-benign errors if a userland program compares a number to a limit that happens to be set to RLIM_INFINITY (an older binary will perform a signed comparison, which will return a different result if RLIM_INFINITY is negative when interpreted as a signed number). But userland programs shouldn't be comparing numbers to limits - that's the kernel's job, and the kernel will always be consistent with itself. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
