The following are the proposed solutions for replicating the packages GNU area without having the read-write path compiled in the packages. I have tried to list the pros and cons for each side, if there are ones that I have missed then email me . Also listed on the bottom are other things to look into before we implement one of these solutions.
Easy installations setup.
Can do on public machines. Easy afs management, one volume for each ostype. This is to have access to all the GNU utilities. We then have to run the linker script to update the .gnulink area. Easy to get rid of old packages, just run a full link on the GNU area.
