[SOLVED]custom iso by mkarchiso says device not found

bingma · 2024-10-31 14:36:43

Mkarchiso produces an iso, but can't boot. I added "noautomount noswap" and cow_spacesize to kernel parameters, and copied linux-libre-firmware (mentioned in AUR) to airootfs, not using linux-firmware from pacman repo. But if I install Arch on hard disk, it can normally boot with linux-libre-firmware (mentioned in AUR) so it seems the firmware is OK, only the custom iso made by mkarchiso can't boot. When booting the custom iso:

Error: device '' not found. Skipping fsck.
/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel-device mapper driver.
Command failed

So is this related to ventoy?
If not, why do you require dm-crypt for? The root partition?
Have you added the relevant hooks to the mkinitcpio?

No, it's not problem of Ventoy, I saw there're unwanted services in airootfs, e.g cloud-init. I don't want cloud-init to boot over network. So I emptied airootfs, but later, mkarchiso says it requires etc/shadow, so I must copy the shadow file into airootfs; But mkarchiso doesn't hint about other necessary files.

Maybe try to just remove the stuff you actually don't want in there instead of deleting everything (you for the most part will need) and then re-adding random, isolated files…

It looks that shadow, mkinitcpio.conf.d, mkinitcpio.d in airootfs/etc are just enough for offline booting.

"Looks like"
Does the system boot?
Also you saird you wiped the entire airootfs, not only airootfs/etc

Arch Linux
