It is a most impressive achievement, and places an incredible amount of software technology into the hands of sophisticated users, sort of for free. Now then, it appears the size of the swap is automatically set at 10,000 blocks in 0.1. This causes swap to not begin and/or end on a cylinder boundary on most systems, as noted by the asterisks printed next to the cylinder numbers in the output of "disklabel -r". In 0.0, not having swap aligned on cylinder boundaries seemed to cause swaps to overwrite part of the filesystem -- at least this was the consensus of the newsgroup a few months ago, and, as a further data point, our overwrite problems went away when we aligned our swap. Unless this has been fixed in 0.1, the symptom will be weird overwrites of files that are't picked up as errors by fsck (which makes sense). -- -- Email info@NeoSoft.com for info on getting Internet access.
