boot halt problem - solution

internet says to edit /etc/grub.d/00_header:

if [ ${recordfail} = 1 ]; then set timeout=-1 else set timeout=${GRUB_TIMEOUT} fi

What is need is just change the 1st timeout from -1 to a value you like and run 'sudo update-grub2'. The value 0 will bypass the menu and any value >=1 is the time of countdown after a unsuccessful boot.

But I couldn't get this to work, so edited the boot/grub/grub.cfg directly:

from: function recordfail { set recordfail=1 if [ -n "${have_grubenv}" ]; then if [ -z "${boot_once}" ]; then save_env recordfail; fi; fi }

to: function recordfail { set recordfail=0 if [ -n "${have_grubenv}" ]; then if [ -z "${boot_once}" ]; then save_env recordfail; fi; fi }

Preventing fsck on boot

http://www.cyberciti.biz/faq/linux-unix-bypassing-fsck/

edit /etc/fstab: on the line with the hard drive (/dev/sda1) change the last number to a 0 (as explained in the link)

now a check will only be performed if explicitly commanded to do so:

ROS electric development VM

  • ip: dynamic
  • system name: uwesub-dev
  • user name: phoenix-dev

Some useful commands/info:

Logging into uwesub (over wifi)

I have added 'hosts' into the virtual machine /etc/hosts file... this means that you do not need to type the ip addresses for uwesub.

I have also generated keys so that you can connect over the network without a password.

To connect to uwesub over wifi: ssh phoenix@uwesub ... I have also added an alias for this sshsub

VERY IMPORTANT: when logging into uwesub, a message will appear stating: New release '12.04.2 LTS' available. Run 'do-release-upgrade' to upgrade to it.

IGNOR THIS... DO NOT UPGRADE UNDER ANY CIRCUMSTANCES
