Referenced in AOSC-Dev/aosc-os-abbs#2107 partially and explained in the following discussion got from AOSC-Dev/aosc-os-abbs#2108:

Sorry but I have to ask here: information for recursive umount after finishing the installation before rebooting the machine?

umount -lf /path/to/mountpoint should do.

I tried with -R saying me that the system was busy a lot of times, I even checked with lsof as suggested saying systemd services running. I got a bit stressed and tried to shutdown normally expecting the filesystem to be unmounted as expected. 9 minutes later I lost the patient waiting with the black screen and the cursor and forced shutdown. I must start the installation again.

Sorry but as far I have not touched so much with bash loops "# for i in dev proc sys; do mount --rbind /$i /mnt/$i; done" get me confused to umount later

So, I should do umount -lf to /mnt/sys, umount -lf to /mnt/proc and finally to /mnt/dev

Is this correct?

PPC wiki should be more clear with these situations. This second case is more a general issue though.

In the end, I could not reproduce the steps from the guide in a way to get a working system, not at least with received instructions and answers to some questions. The boot partition seems to not be find by the pc, so I am going to think that making grub-install without choosing the device too doesn't work itself making available grub (at least) in that boot partition.
