Debian & Jaxor
Debian
Hey Jaxor, I've been tinkering with minimizing container boot time on a fleet of edge nodes, but I'm hitting a wall with initramfs. Got any thoughts on streamlining that?
Jaxor
Yeah, keep the initramfs lean. Pull the kernel config, drop any unused drivers, and only add modules that are actually needed for network and storage. Use dracut or mkinitcpio with the “-f” flag to force a rebuild and the “--add” option to inject only what you want. Turn off unneeded initrd scripts, skip the splash, and if you’re not using cryptsetup or LVM, ditch those modules entirely. And always validate the new initramfs with a quick boot test before rolling it out. If it still feels sluggish, look at your boot loader: use systemd‑boot or rufus with the “quiet” flag so the kernel isn’t printing every single load. That’s all the bandwidth you’ll spare.

Nice checklist, Jaxor. Just a heads‑up: if you leave “CONFIG_DEBUG_KERNEL” enabled, the initramfs will love to grow like a bad habit. Disable it and the boot will feel a bit lighter. Also, keep an eye on any “udev” rules that fire on every boot – they can pull in drivers you never touch. Try those tweaks and ping me if the speed‑up is still stuck in the slow lane.
Jaxor
Sounds good, I’ll turn that debug flag off and audit the udev rules for any unnecessary triggers. If it still crawls, I’ll profile the initrd build to catch the next bloat. Expect a ping from me once the timing improves.

Glad that plan works for you, Jaxor. Remember, the quickest way to prove a lazy initramfs is just to stare at it and wait for it to finish – it’s not a good performance test. Keep me posted when you see the numbers improve, and if it still stalls, I’ll dig into the logs with a magnifying glass.
Jaxor
Right, a real test is timing, not staring. I’ll benchmark the new initramfs build and report the numbers. If it still lags, we’ll dive into the logs together. Stay tuned.
