Some package recommendations turned out to have circular dependencies, such as ghostscript and texlive. Is there a way, short of looking at every package installation page, to find the dependencies so that I can install everything in an efficient manner?
I have seen a tool someone wrote once to go through the BLFS source and
graph all the dependencies, though I can't seem to find where that was.
Otherwise, yes, just read the book and install dependencies as needed.
One approach might be to open the book to some package you eventually
want, for example Firefox, then open a new window/tab with each
dependency (and do the same with each of *their* dependencies) and close
each one as it's installed.
Then of course, make a note of what you installed in what order so that
it's easier next time.

Depends largely on your own needs, really - that's kinda the whole point
of BLFS. The beginning of the book does mention a few packages you might

I suggest you learn what is meant by a "virtual terminal" before trying
to continue with LFS... (hint: Google "linux virtual terminal)
> Finally, as I installed certain BLFS programs, I found that a few required certain modules to be installed in the Linux kernel. Is there a good way to figure this out BEFORE compiling the kernel so that I don't have to recompile it several times?
The BLFS book lists needed kernel options for each package it contains,
and the Index at the end even summarizes all the packages that have that
