I confess that I am on the low end of the grub learning
curve but I need to make one debian system duel-boot with a
different debian version. One version is debian wheezy which I
want to keep because there are some PIC microcontroller
development tools that make just fine in wheezy but the make
process blows sky high with stretch or buster so the answer is to
make a wheezy partition and a newest such as buster partition and
select one of these two at boot time.
I absolutely hate what I call "press and pray" in which
the silent world prevails and you count button presses in the
silence and hope and pray that nothing weird happens.
Failing speech, I know grub can be configured to work
through a serial port if one exists at the time grub is needed.
Is there a good document anywhere dealing with all these
issues?
This very Summer marks 30 years that I have been working
with unix-like systems so like lots of skill-based systems, I am
familiar with the feel of unix but grub has always been that
mystery thing that you automatically say yes to when installing
debian or freebsd. Now, I want to hopefully do something useful
with it. The less extra hardware needed to read grub's output,
the better off we are and I am aware that very little resources
are operational when grub is working.
Thanks
