ToDo_list

 [x] Script should check at beginning whether it was run with superuser priviliges
 [X] 1  ON (1 5 & 7 ARE RELATED) Assistance with parted - count & display how much space you may assign to partitions
 [ ] 2  Investigate why in some cases parted is unable to inform kernel of new partition table
 [x] 3  Network connection - create self test and nice output
 [x] 4  NTP - same as above
 [X] 5  Check if /dev/sdx exist or break script after first failed command
 [ ] 6  PATBEL WORKING ON IT Print commands output in nice way
 [X] 7  Automatic partitioning with single question on which device to use - selecting by nice name (e.g. producent and model + /dev/sdx path), with option to choose if you’d like to perform manual install.
 [X] 8  Country codes should be stripped of entries like ‘posix’ and parsed to more readable format
 [X] 9  Self check if country code is correct
 [X] 10  TZ should be selected automatically if there is only one tz in country
 [X] 11  Tinker on `Is this correct` questions
 [X ] 12  Perform autocheck of mirrorlist and keyring install success.
 [ ] 13  Parse output from pacman 
 [X] 14  AMENDED BY PUDGE, STILL NEEDS MORE DISCUSSION Why last octet of ip address? and why limited from 100 to 245?
 [ ] 15  PATBEL WORKING ON IT Why after reboot there is start job waiting for /sys/subsystem/net/devices/wlan0 ?
 [X] 16  Ask user if he would like to install additional packages
 
 Bug fixes
 
 2/20/2020  Fixed bug in install-base2.sh   
            Changed lines (approx 239 & 240) in "setup static IP address with user supplied static IP" section
            from ethernetdevice=$(ip -r | grep "default via" | awk '{print $5)  to ethernetdevice=$(ip r | awk 'NR==1{print $5}')
            from routerip=$(ip r | grep "default via" | awk '{print3}') to routerip=$(ip r | awk 'NR==1{print $3}')
 TODO list last amended 02/25/2020
 
 The install instructions last amended 03/06/2020
 
 03/06/2020 Feature added   The script will now optionally partition, format, and mount the DATA device
 which will be included in the /etc/fstab by the genfstab command.
 
 03/18/2020 Feature added   The script will not allow the user to choose the EndeavourOS ISO device.  Displays error, then allows retry.
 This works for both the OS device selection and the DATA device selection.
