LiveCD of OpenSolaris in VMWare
By Weijun-Oracle on Aug 26, 2008
So I creates a new Virtual machine with two CD-ROM drives, put the LiveCD in the 1st one and the VMTools into the 2nd. When the system CD boots up, I will be able to install VMTools from the 2nd CD.
This works quite fine for Ubuntu and the VMTools is installed correctly. But for OpenSolaris 2008.05, it cannot be installed, because the file system that contains /usr is not writable.
I guess in Ubuntu the /usr volume is implemented as a cascaded/hybrid file system, most of the files are from the CD, but you can still add/remove/modify files into the memory that shadows the ones on the CD, and this combined file system looks like a single unified one. OpenSolaris should works the same way, I guess it's only that the designers didn't realize that /usr needs to be modified, so they never make this volume cascaded/hybrid.
