Thanks for the quick reply. Seems so:

    # grep FBSDID /usr/src/lib/libjail/jail_getid.c
    __FBSDID("$FreeBSD: stable/12/lib/libjail/jail_getid.c 348297
2019-05-27 02:18:33Z kevans $");
    #
    # ls -l /lib/libjail*
    -r--r--r--  1 root  wheel  31520 May 30 09:12 /lib/libjail.so.1

My full update included a 'svnlite up /usr/src' followed by make
buildworld & make kernel and later make installworld as per
/usr/src/UPDATING. To the very letter, as I always do just to be save. I
do however use WITH_META_MODE="YES" in /etc/src-env.conf to speed up
things. Anything else to look for?
