I tried converting a Bookworm BeagleBone Black image (direct from the
BBB site) to Devuan, following the instructions on the
"bookworm-to-daedalus" page.
I'm accessing the BBB over serial tty (it's headless).

Each time, after the reboot, I lose the login on the serial tty and the
ethernet interface doesn't seem to come up, leaving me with a kernel log
over serial but no way to log in.

I'm installing on an SD-card, so I can remove it and read/write it on my
desktop (but not chroot into it) and could probably tweak the config
from my desktop if I only knew how. The instructions on the page include
installing sysvinit-core.

Does anyone here know the system boot-up process well enough to point me
in right direction?

Thanks in avance,
    Antoine
