after a first successful rootfs mount over NFS (where the system worked perfectly) and after the first reboot (done via sudo halt or sudo reboot commands), I can’t no longer login in to my bb xm. In fact, the login shell does not appear.
I suspect something in the rootfs get corrupted after the first reboot. If I delete this corrupted rootfs and substitute it with a new rootfs (with new I mean untarred from the original .tar and never mounted via nfs), then everything works as expected.
This is the relevant part of my /etc/exports file:
The rootfs I am using is called armel-rootfs-201207162218.tar and it’s contained inside the ubuntu-12.04-r4-minimal-armhf-2012-07-16.tar.xz archive. I obtained it from http://rcn-ee.net/deb/rootfs/precise/ubuntu-12.04-r4-minimal-armhf-2012-07-16.tar.xz
I untarred my rootfs with the command tar -xvf armel-rootfs-201207162218.tar (I tried also with sudo tar -xvf armel-rootfs-201207162218.tar to gain root privileges). No relevant differences noticed.
This is an excerpt from my boot messages (where login prompt doesn’t show up):
