It told me to make the swap smaller, 128MB max for safe use with Linux. About two hours total. I do not know how far this can be pushed. It is sort of between HP Unix and Microsoft. The set of packages was different even when taking into account the slight differences in names.
All distributions have access to all others by mounting each others partitions.
This makes it easy to copy files from one distribution to another or to just execute programs or access data from other distributions.
