Because
1) In the real system there is a lot of symlinks nowdays over
/var, /spool, etc. Mtree can't do anything for them, i.e. change
permissions/owner. I.e. if you have /var/mail -> /somewhere
it will never be changed to group "mail" 775 like -current does now,
symlink totally confuses mtree.
2) Mtree can't deal with symlinks properly in any case (they are created
separately in other places now), so we lost no functionality by making
them invisible for mtree.

found that my syslogd is now running them for several months...
Add an option to syslogd to restrict the IP addresses that are allowed
to log to this syslogd. It's too late to develop the inter-syslogd
communications protocol mentioned in the BUGS section, some 10 years
too late. Thus, restricting the IP address range is about the most
effective change we can do if we want to allow incoming syslog
messages at all.
IMHO, we should encourage the system administrators to use this option,
and thus provide a knob in /etc/rc.* for it, defaulting to -a 127.0.0.1/32
(just as a hint about the usage).
Please state opinions about whether to merge this change into 2.2 or
not (i've got it running on RELENG_2_2 anyway).
Instead, reverse the order of the testing, so if a symbolic name starts with
a digit, we'll see if we can make a network address out of it first. If
that fails, then we'll call getnet...

it's done for pci. This is so that systat and vmstat can get at the

vnconfig doesn't seem to be in Lite2, although dev/vn is. The Lite2
merge in userland has converted all mount calls except this one and
one for devfs in init, so we can drop support for old mount args soon.
Vnconfig probably shouldn't support mounting - it only supports ufs.

I suspect it was because the child exec code's parent was doing the
initial lookups, then forking, then doing other things (possibly trashing
the static data in the getpw*() buffer), then attempting to dereference
*pwd and *lc. Also, no error checking appeared to be done - I've allowed
it to fall back to the old "become user" code on critical failure rather than
risk running a user's cron jobs as root.
Accept SIGHUP as a "re-open logfile" signal. As ppp
doesn't set it's serial line to it's controlling terminal,
we can use HUP :)
This is a candidate for 2.2. The log.[ch] changes won't
conflict, but the main.c changes will. We just want to change the
kill(...,SIGHUP) to a SIGTERM and change the signal(SIGHUP,Hangup)
to a pending_signal(SIGHUP,LogReOpen).
These changes should fix the signal "problems" in ppp.
The signal changes should really be put into 2.2 too !
The following patches should do it. There were some other
changes made by Andrey recently that havn't been brought

dangerous! Signal handlers themself must be fixed to not call malloc,
but no pended handlers, it will be correct fix. In finite case each signal
handler can set some variable which will be analized later, but calling
handler functions manually is too dangerous (f.e. signals not blocked while
the handler or handlers switch executed in this case). Of course this
code can be fixed instead of removing, but it not worth fixing in any case.
Should go into 2.2
In addition sig.c code shows following dangerous fragments (there can be more,
but I stop after two):
This fragment
if (fn == SIG_DFL || fn == SIG_IGN) {
handler[sig-1] = (sig_type)0;
<------------- here
signal(sig,fn);
} else {
cause NULL pointer reference when signal comes
"here", but more worse fragment is below:
void handle_signals() {
int sig;
if (caused)
for (sig=0; sig<__MAXSIG; sig++, caused>>=1)
if (caused&1)
(*handler[sig])(sig+1);
}
caused is bitmask which set corresponding bit on each signal coming.
And now imagine, what happens when some signal comes (bit sets) while loop
is executed (see caused>>=1 !!!)
In this light carrier drop situation was (as gdb shows)
1. SIGSEGV in handle_signals because some junk called as *handler reference.
2. Since SIGSEGV was pended too (== never happens),
it can cause various range of disasters.

All signal() calls have been changed to pending_signal() calls.
pending_signal() is defined in the new sig.c file. It remembers
the handler and traps the signal with a function that will remember
the signal.
main.c now calls handle_signals() to actually call the required
handlers (if the above handler was called).
If this doesn't close PR2662 (was PR2347), I'll cry.
Joerg, I think this should go into 2.2, but I havn't done anything
