                Script to flash an SDHC card with Raspbian
                ==========================================
                

1. Configuration:

   - edit  wpa_supplicant.conf  to replace sample values with the one for your
     WiFi network.

   - edit setup.sh to replace ../2023-02-21-raspios-bullseye-armhf.img.xz with
     the location and file name of your Raspbian install image.

  - optionally, replace usename and/or password in the line stariting out with
    edit" pi:`echo ...

2. Preparation:

   - determine  the device  name of your SDHC card  reader/writer.  Unplug the
     reader,  wait for a minute,  then plug it back in. Run "dmesg -T" to find
     something like sdb, sdc, ...

3. Installation:

   -  invoke,  as  root,  setup.sh,  followed  by the  name of the  SDHC  card
   reader/writer, like as in
   
   ./setup.sh /dev/sdb
   
   Once the script  completes, move the card to the destination Pi, then power
   that up. Watch  your  router's  DHCP  device  list page for the new Pi's IP
   address, then ssh into it using the password from the installation script.
   
   At its very first start, Raspbian expands the installation image's to cover
   the whole, configures the user account  requested by the setup script and a
   couple other  things, then  reboots.  Depending on which kind of Pi you are
   setting up, this might take a few minutes.
