  • I went camping once with my dad and a few of his buddies when it was frigid cold outside. We piled 5 adult bodies into a camper, and they also left a Coleman gas lantern lit inside the camper all night for warmth.

    I couldn’t sleep for two reasons:

    1. One of my dad’s buddies had horrible snoring, and

    2. I could feel myself choking on the stale air. I ventured outside every so often and would hold the camper door open for a few minutes (or until I would get yelled at). I don’t remember 100% but I think I had a persistent headache that night.

    I’m still convinced we could have all died.











  • I’m using Gentoo with systemd and a customized kernel, and additionally I have the /usr partition LUKS encrypted. Because /usr is absolutely essential for systemd to function, I configured dracut to make a specially crafted initrd which activates the luks lvm and prompts for the password to decrypt and mount /usr on startup before systemd init tries to run.

    About a year or two ago, some update to dracut or some other dependency (assumption) caused the dracut generated initrd’s to kernel panic. After multiple days of troubleshooting, I discovered that just copying forward an older initrd in /boot and naming it to match the new kernel, e.g. initramfs-6.6.38-gentoo.img , allows the system to boot normally .

    So, my Gentoo is booting a kernel 6.6.something with a ramdisk generated in the 5.9 kernel era. I am dreading the day when this behavior breaks and I can no longer update my kernel 😳
