I've been running CURRENT with DEBUG_FLAGS=-ggdb in make.conf for a long
time. It helps a *lot* when there is a core dump to have symbols in all
the system libraries and binaries:
root@kobe:/root# nm /bin/ls | grep ' [TDB] [[:alpha:]]' | head -3
08049760 T acccmp
0804e42c B ansi_bgcol
0804e400 B ansi_coloff
...
I'm definitely in favor of making DEBUG_FLAGS=-ggdb on CURRENT and
STABLE, but there's probably a small catch we have to consider: What to
do about freebsd-update that crosses the boundary from -RELEASE to
one of the -STABLE snapshots. If there are no hidden gotchas about
running a system that is half-release/half-stable, then we should be
fine. But it may be a good idea to update *all* the binaries at the
crossing point, so that people don't have a base installation that only
includes debug symbols for a small subset of the binaries.
