Asunto: Re: [DNG] How to integrate devuan-installer in an existing devuan based system
I forgot umounting the partitions:

umount chroot/proc
umount chroot/sys
umount chroot/dev/pts

after exiting from the chroot jail. Be sure that chroot/proc and
chroot/sys are empty, because sometimes they are busy. Otherwise,
restart the computer.
