I recently migrated my second Debian Jessie VPS to Devuan Jessie following the guide here https://git.devuan.org/dev1fanboy/Upgra … -to-Devuan. The first time I migrated a VPS I did not have any trouble. A few months later, I tried a 2nd VPS and after I reboot, I got an error from the console asking me to Enter Runlevel. No run level entries, from 0 to 5 work.

In my case the error was due to missing or blank /etc/inittab file. I re-imaged debian jessie to VPS, and checked the default. Sure enough, /etc/inittab was blank. I added one from another Devuan install, and then did the migration again. The migration worked.

I'm not sure why the hosting company decided to remove /etc/inittab. But after replacing it, the migration to devuan worked.
