[ML] I think you have misunderstood: FreeBSD uses only one (primary) DOS/Linux partition (FreeBSD calls this slice). It repartitions this slice afterwards into its own partitions. So, if you have reserved more than one DOS partition (slice) for BSD, and they are contiguous, you can merge them together and install FreeBSD on that. Normaly, there is always only one BSD slice on disk which is then split into more BSD partitions. BSD does not touch other slices (but caution is nevertheless a good advice). However, the DOS/Linux style partition (BSD slice) has to be a primary partition: BSD cannot subpartition an extended DOS/Linux partition. 64 Megs of swap may or may not be enough, depending on your job mix: FreeBSD prefers keeping recently used pages (even if they are clean) over the not so recently used dirty pages in cache; it also swaps out clean executable pages out in idle periods so that an app needing new memory does not need to wait for swapout. The result is that it pages out (much) more aggressively than Linux, for example, but has much better response under load and memory hungry apps. Naturally, when the swap is short, it will throw away the clean buffers, degrading its performance. /Marino To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
