You're being absurd. local.sqlite is nothing like the Microsoft
registry[*]. It's a database of all the files etc. that are managed
through the ports system. No more, no less.
All we have done is replace an unreliable collection of text files --
hard to keep consistent, impossible to update in an atomic fashion and
woefully pessimal for certain quite legitimate queries -- with a RDBMS,
which quite neatly disposes of those problems. No, it isn't ascii text
which you can grep through. It's a set of relational tables, which you
can query using SQL. And that is a deal more powerful in many ways than
grep, but not so familiar to most; so we've provided a scripting
interface in the form pf pkg-query(8).
Do you complain because ZFS doesn't have it's configuration data in some
ascii text files? How about procstat(8)? Or ld.so(1)/ldconfig(8)?
Truth is, unix has always adopted a pragmatic approach to system data
and stored it in whatever form would be most effective. In our case,
we're pretty clear that a relational database is streaks ahead of a
directory tree full of text files.
[*] Quite apart from anything else, a corrupt local.sqlite doesn't make
one iota of difference to the operational effectiveness of your system.
All it means is you've lost track of what port installed what file.
