The X-Window Disk Druid has a few problems: 1) It doesn't recognise Solaris partitions. Naughty! It sees them as Linux Swap which is fair enough given that they have the same partition id, but then there is no way to change the mount point from <swap> to <not set>. I don't want to overwrite Solaris data with Linux swap. The current workaround is to use a partition manager to fake the id of the solaris partition as something else during the Linux installation. 2) The installer refuses to show a Next button until a swap partition is defined. I don't want one since I have 128M RAM. I use Solaris x86 fine without a swap partition! 3) I can't define a root "/" partition greater than 1882M. Why not? It just complains "root partition too big".
We were hoping that we had fixed problem #1, but apparently we did not. Sorry about that . . . we will put it in the list for next release. You should be able to install in expert mode (type "expert" at the boot prompt) and that should allow you to get past the requirement of having a swap partition. The other option is to create a 1M swap partition and just delete it after you reboot the machine (remember to remove it from /etc/fstab as well) Problem #3 is a confusing situation, but what is really happening is that the installer is trying to tell you that the BIOS on your computer will not allow booting from a partition which is not within the first 1024 sectors of the drive. The best way to get around this it to create a small (16-32M) /boot partition and then create your root partition. With this setup, the installer will let you create as large a root partition as your drives will handle.
