However, a Solaris 8 x86 vanilla install on VMware I did recently does indeed have swap on the first cylinders (see below). A Solaris 7 x86 install does not exhibit this behavior. Now I'm wondering if Solaris 9 does it. A Solaris 10 box I have access to has swap after root, not before. # format Searching for disks...done AVAILABLE DISK SELECTIONS:        0. c0d0           /pci at 0,0/pci-ide at 7,1/ide at 0/cmdk at 0,0 Specify disk (enter its number): 0 selecting c0d0 Controller working list found [disk formatted, defect list found] Warning: Current Disk has mounted partitions.
