Updated #FreeBSD today: started with "14-CURRENT"; ended with "14-STABLE".
Kernel building was exciting for the KERNCONF could not be found Initially I thought the problem could be more ... problematic. Turned out that "GENERIC-NODEBUG" was merely gone. No wonder. Well, after substituting a kernel configuration sans "COMPAT_FREEBSD[0-9]" everything was fine again
(Man! "GENERIC" configuration has lots of crap! Best is not to look at it.)
Until "#etcupdate -[pB]". That reported "conflicts" with a version of "/etc/{group,master.passwd}" (along with log rotation changes for "pf" & "sendmail" files). Of course it did Kept own versions (by eliding the undesired conflict marker, state).
