SystemTap in Gentoo

If you didn’t know already, SystemTap is in Gentoo’s public portage tree. Just try an “emerge systemtap” and it should work. Just make sure to have both relayfs and kprobes enabled in your kernel before the emerge. [[updated: I've been told procfs works as well and relayfs is not a requirement]]]
I just met with Stephen O’Grady and had an IBMer brief him on SystemTap while in Boston for LinuxWorld last week. He put together a nice write up on his blog over here.
Stephen also pointed out a cool derivative of top called ‘htop’ - just ‘emerge htop’ and take a look.
