If so, be careful when installing it. I tried installing it on a machine with two other systems installed. It failed to install (looped trying to install drivers it didn't need). When I rebooted, I found that it had overwritten the Master Boot Record (which is silly, since it knew there were two other systems on the disk), and it also rewrote the partition table: it changed the numbers of the partitions. This is particularly difficult for FreeBSD, which has the partition number explicitly in the device name. In my case, FreeBSD was on partition 2, devices /dev/rwd0s2a and /dev/rwd0s2e. It was moved to partition 3, so the device names changed to devices /dev/rwd0s3a and /dev/rwd0s3e. Since I didn't have device nodes for these devices, I was unable to remount the root file system, and I had to use the fixit floppy to rewrite the partition table. Nothing got lost, but it was a real pain. Greg -- When replying to this message, please copy the original recipients.
