DHCP 4.2.4 install overwriting dhcpd.conf

[Lyle Giese]

I have a failover pair that was running ISC DHCP 4.1.1(built from source 
downloaded from www.isc.org).  I needed to replace one of the servers 
and I downloaded DHCP 4.2.4 from www.isc.org and installed it on the new 
server.

On the new server, I ran make install and then placed the old dhcpd.conf 
and dhcpd.leases in place and started the daemon on the new server and 
all was well.

Today, I got around to updating the old server so that it would be 
running the newer version.  I downloaded DHCP 4.2.4 and compiled it.  I 
ran ./configure, then make, stopped the old daemon, ran make install and 
then started the new version.  I start the daemon via:

/usr/sbin/dhcpd -4 -cf /usr/etc/dhcpd.conf -lf /usr/etc/dhcpd.lease

I was quite surprised that 'make install' overwrote the existing 
dhcpd.conf with it's default.  I had to go back to my backups and 
restore that file.  Then the daemon started normally and read in the 
dhcpd.lease file just fine.

I don't think the install should be overwriting existing config files.  
This is one of the few times I have seen that happen when installing 
from source.

For what it's worth this system is running SLES 11 kernel 
2.6.27.19-5-default 64 bit SMP.
