From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

TIFU by rebooting before rebuilding my initfs (lemmy.world)

I had a super fast but small SSD and didn't know what to do with it, so I was playing with caching slow spinning LVM drives. It worked pretty good, but I got interrupted and came back a few weeks later to upgrade the OS. I forgot about the caching LVM, updated the packages in preparation for the OS upgrade, then rebooted. The LVM cache modules weren't in the initfs image and it didn't boot.

I should know better. I used to roll my own kernels since Slackware 1.0. I've had build initfs images for performance tweaks. Ugh!

Where's my rescue disk?

A Gentoo LiveUSB and some chroot would save your day!

Adding a netboot.xyz EFI boot menu entry can be useful if you do not need a live system often and do not have a USB stick when you do.

But don't you need a wired network connection for this to actually work?

[–] [email protected] 1 points 8 months ago

I have only tried it with wired but it uses ipxe and that is supposed to work with Android USB tethering too to bridge to other kinds of network access.

I have the Debian netinst disk, but it doesn't include the dm-cache modules, so I downloaded the live DVD last night. I only get about an hour a day to work on stuff.
