I am thinking about moving pcre from BLFS to LFS. The latest less now
supports pcre and pcre2 and grep also supports pcre. It should be pretty
stand alone as the only dependency is (optionally) valgrind.
If added, I would place it in Chapter 6 just before grep.
There are 19 references to pcre in BLFS (and 6 to pcre2).
What do you think?

As it happens, I currently build both before trying to boot. But
I don't see the point of moving it. We've known for a long time
that grep can use it, and we cover that. I remember when LFS was
small - many things have been added, but the justification for
adding pcre or pcre2 seems weak to me.
More importantly, I think we should not be encouraging people to
use pcre (instead of pcre2). While things in BLFS still needs it,
fine - but it should eventually drop out. ISTR that the
vulnerability fixes in the last couple of years did not get an
updated release for quite a long while, unlike pcre2.

I concur here, especially because of vulnerabilities that are still not
fixed upstream. This appears to be because upstream has focused efforts
on PCRE2 instead (which makes sense), but I'm not 100% sure.
I think we should keep things the way that they are here.
