Just wanted to drop a quick note saying Slicehost has finally released a new kernel that fixes all of the issues I had pointed out in the
2.6.31-302-rs build. It took a whole lot longer than I would have wanted—nearly three months—but it does seem to be working great so maybe one could say it was worth the wait.
The new kernel has a version of
220.127.116.11-rscloud. It includes both the
xt_recent kernel module, used for my iptables rate-limiting rules on the SSH port, and also has a much smaller memory footprint with none of the JFS and XFS junk stealing valuable megabytes of RAM. If you are running Arch Linux on your slice, I would highly recommend updating to this kernel.
Edit: Now that 18.104.22.168-rscloud is out, you should probably use that instead.
