GDM Autologin (revisited)

The following is the configuration for that.

1) install RHEL7.3 with minimum install
2) install gdm and dependencies
3) install motif, xterm, xorg-x11-fonts-*, xorg-x11-server-Xorg and xorg-x11-xinit-session
4) systemctl set-default graphical.target
5) create /root/.Xclients  (This is called from /etc/X11/xinit/xinitrc)
-----------
#!/bin/sh
xclock -geometry +0+0 &
xterm -ls &

exec /usr/bin/mwm -multiscreen
------------

6) create /root/.xsession  (This is called from /usr/libexec/xinit-compat)
------------
#!/bin/sh
exec /etc/X11/xinit/xinitrc
------------

7) set exec permission to /root/.Xclients and ~/.xsession

# chmod gu+x /root/.Xclients /root/.xsession

8) create /etc/sysconfig/desktop. This is to disable gnome and kde completely
------------
unset GSESSION
unset STARTKDE
------------

9) create /etc/gdm/custom.conf. This is to enable automatic login with root user.
--------------
[daemon]
AutomaticLogin=root
AutomaticLoginEnable=True
--------------

Reboot, and mwm should start on the screen without any login step.

PXE boot a LiveCD image

Summary: I have wanted to build a kickstart environment which hosted a "rescue CD" or LiveCD to allow you to boot over the network after you blew your stuff up and needed to repair a few things.  Today I have worked through a method of doing so, with the help of the people who published a succinct script with the Red Hat Enterprise Virtualization Hypervisor.  (the script will be at the bottom of this post - if I have somehow not followed the GPL, please let me know and I will correct whatever is necessary) NOTE/Warning: The boot will fail due the initrd being too large (645mb).  I'm not sure how to proceed.  This procedure worked for RHEVh, because it is quite a bit smaller.  Hopefully I can report back with progress on this? :-$ Procedure: download your LiveCD image to /export/isos/RESCUE/Fedora-16-i686-Live-Desktop.iso # cd /var/tmp # vi livecd-iso-to-pxeboot (populate the file with the script shown below) # chmod 754 ./livecd-iso-to-pxeb...

"Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)" One issue that may cause this to arise is if you managed to break your /etc/fstab We had an engineer add a line with the intended options of "nfsvers=3" but instead added "-onfsvers=3" and it broke the system fairly catastrophically.

MOTD with colors! (also applies to shell profiles)

I'm not sure why I had never looked into this before, but this evening I became obsessed with discovering how to present different colored text in the /etc/motd. A person had suggested creating a shell script (rather than using special editing modes in vi, or something) and I agree that is the simplest way of getting this accomplished quickly. This most noteworthy portion of this script is the following: RESET="\033[0m" that puts the users shell back to the original color. I typically like a green text on black background. Also - a great reference for the different colors and font-type (underscore, etc...) https://wiki.archlinux.org/index.php/Color_Bash_Prompt I found this example on the web and I wish I could recall where so that I could provide credit to that person. #!/bin/bash #define the filename to use as output motd="/etc/motd" # Collect useful information about your system # $USER is automatically defined HOSTNAME=`uname -n` KERNEL=`un...
