Maybe this is a naive question, but I'm curious. The LiveUSB/CD version of Slitaz runs by default off the computer's memory. Where as the hard drive install does not do that, although you can force it do so by using the loram option (?).
What is the rationale behind forcing the hard drive install to run off the disk vs RAM? Considering most systems these days have plenty of memory (north of 1GB), memory consumption should definitely not be an issue, especially considering Slitaz's extremely low resource footprint (with a dozen applications running, my memory usage rarely crosses 200MB).
The difference in performance between the two modes is tremendous, the system operates at a lightening fast speed when running off the RAM, vs when off the disk, it is pretty ordinary. This is especially true for older systems that still have plenty of memory, but not the fastest processors (my 6 yr old laptop for example, is running on an Intel Core Solo but has 2 GB RAM).
