This is just one more live example for partitions vs disks setups.Well, they did use partitions, but what do you do when the new RAID controller bites off a whopping 100 million bytes from the end of your disk? I use partitions too, and do leave some space at the end for cases like this, but what I leave is just 8 MB (enough for the Gigabyte motherboards HPA), not 100+. Would you suggest setting aside 500MB, 1GB just in case?
I've always (well, after switching to partitions) used something near
80mb, for the last servers using ~ 160mb
