Subject:   "poudriere bulk -w" use vs. kern.corefile=/var/crash/%N.%P.core

I classically run FreeBSD with:

# more /etc/sysctl.conf=20
kern.corefile=3D/var/crash/%N.%P.core

But I've discovered that for "poudriere build -w" use
this means that the likes of:

=
/usr/local/poudriere/data/wrkdirs/zrFBSDx64Cjail-default/default/ghc-8.0.2=
_1.tbz

ends up without the core file from the failed build involved.

So I've reverted to:

# more /etc/sysctl.conf=20
kern.corefile=3D%N.%P.core

which then gets me things like (from trying with the
adjusted context):

# tar xf =
/usr/local/poudriere/data/wrkdirs/zrFBSDx64Cjail-default/default/ghc-8.0.2=
_1.tbz                                                                   =
                   # find . -name "*.core" -print                        =
                                                                         =
                                                            =
./work/ghc-8.0.2/ghc.29907.core

Outside poudriere I normally prefer to a void
having .core files left in various places.


The jail context here is based on:

~/sys_build_scripts.amd64-host/make_amd64_nodebug_clang-amd64-host.sh =
-j8 installworld distrib-dirs distribution =
DESTDIR=3D/usr/obj/DESTDIRs/clang-amd64-installworld-dist DB_FROM_SRC=3D1

~/sys_build_scripts.amd64-host/make_amd64_nodebug_clang-amd64-host.sh =
delete-old delete-old-libs -DBATCH_DELETE_OLD_FILES =
DESTDIR=3D/usr/obj/DESTDIRs/clang-amd64-installworld-dist DB_FROM_SRC=3D1

poudriere jail -c -j zrFBSDx64Cjail -m null -M =
/usr/obj/DESTDIRs/clang-amd64-installworld-dist -S /usr/src -v =
12.0-CURRENT

But the behavior is tied to the live system's /etc/sysctl.conf
(or the last live setting from a "sysctl kern.corefile=3D. . ."
before the:

/usr/bin/nohup poudriere bulk -j zrFBSDx64Cjail -w . . .

run if then left alone).

Note: My jail context here depends on a local workaround
for this style of jail construction:

This is because the ${UNAME} use generates empty strings
and those in turn lead to poudriere rejecting the
attempted builds for version comparison mismatches
with _OSRELEASE involved.
