7/13/2018 - comet2 machine arrives in bldg 48 rm 248. Kerberos authentication (temporary). Initial pass at identifying and installing needed software packages (above table)

8/28/2018 - comet2 rebuilt, lose login ability

9/28/2018 - regain ability to login via local account. Re-install needed packages. Also move offending file which causes polkitd to consume too much CPU, "A workaround that I've been using is to remove /etc/xdg/autostart/org.gnome.SettingsDaemon.Account.desktop until the above mentioned bug is fixed." (but this does not clear up the issue - polkitd still consumes 7-6% of the CPU continuously)

11/13/2018 - chef client installed (by Karl). Unexpectedly (to TG), this also activated unix kerberos authentication, thus I begin to use the 'dragon' (SLAC) account in favor of the dragon1 (local) account on comet2.

12/17/2018 - Karl adds 'dragon1' and 'dragon' accounts to /etc/group 'wheel' group. This allows a user to run, for example, the software installation tool GUI launched from the Applications -> System Tools menu in the WM.

12/19/2018 - Karl adds 'dragon' to sudo list.

1/14/2019 - Add system monitor to "top panel" in Gnome3 (right-click in that area no allows one to add new widgets): Applications->System Tools->Application Installer->Add-ons

1/18/2019 - Erik Chavez kindly provided two displayPort-to-DVI adaptors and that seems to work just fine with default display driver, etc.

1/22/2019 - install 'hdparm' on comet2 in anticipation of running with SSD. Use: "lsblk" to determine the device for the HDD/SSD, then "hdparm -I /dev/sda2" for details. (Current HDD is Western Digital 160 GB drive.)

1/24/2019 - Karl installed GTK+ v3, enabling build of galculator (./configure, make, make install).

1/24/2019 - Attempt to update BIOS on comet2 (from A26 -> A30). After multiple attempts, was unable to produce a bootable FreeDOS USB device using parted & unetbootin on comet2. However, using rufus (http://rufus.akeo.ie/) on a Win10 machine was trivial (and successful). BIOS was updated to version A30 on 1/25/2019. Hint: rename the Dell bios updater app so that it has 6 or fewer characters, or it will be abbreviated by DOS.

1/25/2019 - Reduce those huge desktop icons with

'gsettings set org.gnome.nautilus.icon-view default-zoom-level small'

1/30/2019 - 'sudo yum install redhat-support-tool' and search for data on SSD/trim support in RHEL.

2/19/2019 - Install 1 TB SSD in comet2 using partitioning scheme above. Andrew activates kerberos and adds me to sudo list. Then begin process of installing needed software all over again!

2/20/2018 - X11 install appears successful, but causes screen freeze. Also SELinux complaints...but Karl fixes:

    sudo semanage fcontext -a -t abrt_var_log_t '/var/adm'
    sudo restorecon -v '/var/adm'
    sudo systemctl restart rsyslog
