This could be extremely helpful for initrd, say for live distributions: you could then add content to say /lib/modules without having to play the unmkinitramfs

This could be extremely helpful for initrd, say for live distributions: you could then add content to say /lib/modules without having to play the unmkinitramfs and multiple cpio dance like https://askubuntu.com/questions/1435396/load-drivers-to-initrd https://askubuntu.com/questions/1435396/load-drivers-to-init...
- rwmj 4y agoDusty has something similar to this in mind. Specifically he would like to support multiple clouds (hence a variety of drivers and guest agents) using a single main image.
- dezgeg 4y agoInitramfs archives have a little-known secret: you can simply concatenate them even when they are compressed and the kernel will parse them all. So appending stuff doesn't need unmkinitramfs (which is indeed painful due to needing to keep permissions correct etc.)
