Due to a missing character in a change to olpc-os-builder[*], 12.1.0 os13 builds do not have any working Linux console terminals, and will repeatedly try to set permissions on the /dev directory to 0600 (root-only read/write) while trying to restart said terminals.<br>
<br>This permissions change on /dev will then break a lot of applications and scripts.<br><br>To fix this, try to get into a Terminal program in Sugar or GNOME as fast as you can, or use the serial port console (which is not time-restricted).<br>
<br>Then:<br><ol><li>As root or via sudo, edit the /usr/lib/systemd/system/getty@.service file. Change the line:<br><br>ExecStart=-/sbin/mingetty --loginpause --autologin root --noclear %<br><br>to read<br><br>ExecStart=-/sbin/mingetty --loginpause --autologin root --noclear %I<br>
<br>by adding the capital letter "I" onto the end of the string.<br><br></li><li>Run "sudo systemctl restart getty@tty2.service". Repeat this replacing "tty2" with "tty3", then "tty4".<br>
<br></li><li>Run "sudo chmod 755 /dev".<br><br></li><li>Reboot your XO via the "reboot" command or the GUI to make sure nothing is hung waiting on something in the /dev directory.<br></li></ol>[*] <a href="http://dev.laptop.org/git/projects/olpc-os-builder/commit/?id=a9b4e062c9cbe809b26d97264068a6bc5c2e2824">http://dev.laptop.org/git/projects/olpc-os-builder/commit/?id=a9b4e062c9cbe809b26d97264068a6bc5c2e2824</a><br>

For your interest, os13 for XO-1.75 contains firmware Q4D16, which<br>
incorrectly displays the processor core frequency. The core continues<br>
to run at 800 MHz even though it may show as either 910 MHz or 800<br>
MHz.<br>
