[pkg-dhcp-devel] Bug#798177: "Use default paths for lease files" breaks dhcpd

[Iustin Pop]

Package: isc-dhcp-server
Version: 4.3.3-2
Severity: important

Hi,

The changelog for "isc-dhcp (4.3.3-2) unstable" says:

"* Use default paths for lease files."

I don't know what the actual change was here, but the result is that dhcpd
expects the lease file to live in /var/db/dhcpd.leases, which is not where the
lease file was before and is not policy compliant. Policy aside, it breaks the
startup, since the init script still touches /var/lib/dhcp/dhcpd.leases.

Note:

# grep leases /etc/init.d/isc-dhcp-server 
        touch /var/lib/dhcp/dhcpd.leases

# strings $(which dhcpd)|grep -F .leases
/var/db/dhcpd6.leases
/var/db/dhcpd.leases

The change in git simply removes the configure options for --with-srv and
--with-cli lease, noting that it fixes bug 758882. I don't see how that will
fix r/w files in /var, since the default lease files are still in /var.

Please investigate and update the change. The server lease file was in the
right place, the client one might need to be put somewhere else, but right now
the fix breaks more than it solves.
