Not being one to give up easily, I attempted a redirect maneuver:
> GRUB_CMDLINE_LINUX_DEFAULT="text" >>
/home/User/Documents/ShutdownBlinkies/text.txt (typo corrected !)
And ... sure enough, there's a file at the appointed place (text.txt) but
it's empty ... sigh.
However, there has been progress:
When I exited the console with sudo shutdown -h now, the elusive blinkie text
appeared for what seemed an eternity, long enough for me to "read" it, but
not long enough for me to memorize it (maybe 1/4 second). It contained a
reference to www-data, a user whom I thought I had sent to /dev/null, which
is still disturbing me, if not anyone else ...
If only I could redirect that "sudo shutdown -h now" output to a file of its
own ...
Why not ? I'll try "sudo shutdown -h now >>
/home/User/Documents/ShutdownBlinkies/text.txt"
