I’ve updated the Gutsy howto for version 1.1. There are quite a few additions, and a number of minor clarifications. Most of the changes are superficial — typos here and there, or corrections to the grammar — but there are some noteworthy inclusions.
I made a note about Midori after playing with it the other day. And I added the vm.vfs_cache_pressure trick, which might help under particular circumstances. There are quite a few more changes; check the version history.
Don’t look for a v1.2 for a while. I don’t think I’ll be able to fish out enough changes to warrant another update. But of course, if you have ideas, I’m always listening. … ;)
