You might want to start using jhalfs for tests. I understand you want to
experiment a bit, but if you want to revert, you can just point it to a
different, or modified, version of the book.
I admit I have a pretty fast system. but the other day I did a build at
-j10 without any tests and it only took 48 minutes for everything except
actually building the kernel. You can also modify the scripts manually
for individual packages and set breakpoints.
I am not suggesting that you change your overall methodology, but perhaps
add another tool to your toolbox.
My basic method is:
Make changes to the book in my sandbox
Build the book
# Umount any current virt fs & erase everything on /mnt/lfs except sources
