Key phrase, in main:=20


# For full debugger support use (turn off in stable branch):


Most recently (12th August) for amd64, a main view of the=20
twelve options that are _not always_ needed:=20

So, for example, in stable/13 for amd64 we see the=20
two options, alone, that are _always_ needed:=20

<https://github.com/freebsd/freebsd-src/blob/0ca1220443695c79849bf0807306d0=
864acbabb9/sys/amd64/conf/GENERIC#L92-L94>


options         KDB                     # Enable kernel debugger support.
options         KDB_TRACE               # Print a stack trace for a panic.

Notes to self
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

After not easily finding a GitHub method to compare the same file in two
branches, I took a hint from <https://stackoverflow.com/a/59315113/38108>; f=
or a
web-based view of differences. Then, taking a hint from
<https://juplo.de/compare-two-files-in-different-branches-with-git/>:=20

git -C /usr/src diff remotes/origin/main:sys/amd64/conf/GENERIC
remotes/origin/stable/13:sys/amd64/conf/GENERIC | less

Context (my configuration):=20

% git -C /usr/src config --get remote.origin.url
https://github.com/grahamperrin/freebsd-src.git
% git -C /usr/src config --get remote.upstream.url
