standard explicitly disallows passing setenv a name with a '=' in
it but historic BSD behavior is to allow this but to ignore the '='
and anything after it.

hint from claudio@, ok millert@

i remember we already had the confusion and bgpd doesn't have the endpwent

reply instead of doing it in ntpd itself by getting the time we read
from the socket. based on a diff from mickey hacked in shape by me,
lots of testing and review from ckuethe and sthen, theo and claudio like it
too

(although for now our cd images fail to boot on IP27 and IP30).

1) replace +%e by +%d, unescaped blanks don't work at all in file names
2) replace +%b by +%m to make log files sort better by month
3) replace the home-grown +%Y.%m.%d by the standard +%F (= +%Y-%m-%d)

1) advertise *.local and next_part near the top of the three scripts
2) daily: mention smtpd(8) mailq behaviour (like for sendmail, postfix, exim)
3) weekly: drop a comment trivially rehashing the next two lines of code
documenting next_part in the scripts was suggested by jmc@
ok sthen@ okan@ halex@; "i won't object" ajacoutot@

useful for example for release(8) DESTDIRs, ro-mounted foreign OS
partitions, nosuid+nodev-mounted backup areas and the like
while here, do not call ls w/o args in case find returns nothing
based on a patch from halex@, re-implemented by me; variable naming by jmc@
ok halex@ jmc@

Do not attempt to copy a larger partition onto a smaller one.
Backup of non-ffs root partitions was never supported, so don't even try.
(Both of the above suggested by guenther@).
Also add error messages in case ROOTBACKUP is switched on but severely
misconfigured - those were silently ignored in the past:
/altroot not defined or wrong type or on the same device as root.
otto@ agrees that checking the sizes makes sense

crontab(1) does.
ok miod@

and mention this in the Makefile so that this hopefully doesn't get broken
next time the size is modified. Repairs install45.iso.

suggested, tweaked and ok by guenther@

error out.
Add a new user _rwalld for rpc.rwalld, and use that instead
of nobody, also unconditionally drop to _rwalld not only
if rpc.rwalld was started with euid 0 (as root).

"fine by me. it's maybe not ideal, but it's better" jmc@

i.e. rely on the PATH set up in the root crontab(5)
in case /usr/local/bin is needed, daily.local is a logical place to append it

shortening the script by 100 lines and making it easier to understand
no functional change intended
feedback and ok  sthen@ ajacoutot@ okan@

machinery minimally cope with this.
Discussed with and reluctantely accepted by deraadt@; we both dislike
losing the ``naturally comes out of your fingers'' kernel names and the
``one size fits all'' logic; but for now I don't see any easy way to
get a single kernel binary able to run on multiple IP## flavours.

the first query we will never do the settime because
SENSOR_QUERY_INTERVAL (30s) is greater than SETTIME_TIMEOUT (15s).  so
during the settime period only, be more aggressive and use
SETTIME_TIMEOUT/3 for the query interval.

When set to 0, daily(8) won't send mail unless there is something to report.
Using feedback from kettenis@ henning@ jmc@

add the same infrastructure to daily; silencing daily needs another step
