kata-dev-irc-bot<harshal.patil> Very interesting PR, https://github.com/kata-containers/runtime/pull/9806:03
kata-dev-irc-bot<harshal.patil> Is there any doc on how to generate this custom initrd (since it needs to have kata-agent bundled in) ?06:03
kata-dev-irc-bot<harshal.patil> @bergwolf ^^06:05
kata-dev-irc-bot<bergwolf> @harshal.patil https://github.com/kata-containers/osbuilder can be used to create initrd06:41
kata-dev-irc-bot<bergwolf> e.g., I used the following cmd `AGENT_INIT=yes DISTRO=alpine USE_DOCKER=yes KERNEL_MODULES_DIR=/golang/src/github.com/hyperhq/hyperstart/build/arch/x86_64/modules/4.12.4-hyper make initrd`06:42
kata-dev-irc-bot<bergwolf> I'll add something in the dev guild to tell how to build and setup initrd based booting properly06:58

kata-dev-irc-bot<jonolson> Related to the above -- has anyone played around with initrd versus file-backed fake-NVDIMM based booting? I'm wondering if, particularly when multiple containers are launched in succession if the NVDIMM approach leads to happier performance due to data being already-available in the host block cache.16:15

kata-dev-irc-bot<eric.ernst> @jonolson I haven't, but would love to see data from that experiment.17:11
gwhaleyeernst: I'd run that data, but it is easter break here and I have other stuff to do !...17:25
kata-dev-irc-bot<eric.ernst> :slightly_smiling_face:17:26
gwhaleyif somebody were going to try - you should be able to gather some data using https://github.com/clearcontainers/tests/blob/master/metrics/time/launch_times.sh17:27
gwhaleyand then get a quick glance overview of the results using https://github.com/clearcontainers/tests/tree/master/cmd/checkmetrics17:28
gwhaleywell, that is what I'd do - but then I wrote them ;-)17:28
