Why cripple the OS in an attempt > to do away with swap space? Well, no, you can't do _this_. :-) The `ramdisk' in BSD is rather a VMdisk, i.e. it will be backed with the normal paging area. Hence all you'd get by using it to create a swap file would be increased overhead. For an embedded installation (and if you're sure that your programs don't run out of VM), it's not unusual to not use swap at all. Since this is nothing you would setup using sysinstall however ;-), it's irrelevant to the question whether sysinstall insists on configuring swap or not. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
