We've just received a BeagleBone for our project. For this purpose we
don't need a full UI Linux distribution, so we decided to build ours
through the narcissus image builder (Angstrom). But we can't login on
the board after the boot is finish, the root login doesn't work
("Login incorrect"), but there is some error at the startup.
After few tests it seems that the board doesn't do a "first" complete
boot creating some files, etc.
I got it to work by simply removing the /etc/securetty file (simple rename will do). This allows root to log in on any interface. However, I just noticed that my root file system is mounted as readonly… oops
For more info (and alternative solutions )read the man pages for login.
