+++ This bug was initially created as a clone of Bug #468436 +++

Apparently introduced with NetworkManager. Anaconda no longer generates a default vendor class id in DHCP request for network installs.

Additionally, the dhcpclass= option appears to have no affect.

--- Additional comment from dcantrell@redhat.com on 2008-10-24 18:11:34 EDT ---

Since we're using NetworkManager in anaconda now, the proper way to get the dhcpclass= parameter to dhclient is to add a line to /etc/dhclient-DEVICE.conf and let NetworkManager pick that up.

I've patched anaconda to do just this.  This change will be in anaconda-11.4.1.51-1.  Once that appears in rawhide, can you test it out and if it works, and report findings here?

Thanks.

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

Verified fixed in f10. Now dhcpclass= works. And is *required* for legacy behavior of DHCP option 60.

Re-opening. This bug is back in Rawhide.

Even with dhcpclass=anaconda there is no more Option 60 in the lease request.

This is now a problem in NetworkManager.  When NM builds /var/run/nm-dhclient-ethX.conf, it's not copying over the settings from /etc/dhcp/dhclient-ethX.conf.  Here's a patch for NetworkManager:

diff --git a/src/dhcp-manager/nm-dhcp-dhclient.c b/src/dhcp-manager/nm-dhcp-dhcl
index ac7d9f5..c1f76c2 100644

        orig = g_strdup (SYSCONFDIR "/dhclient.conf");
 #elif defined(TARGET_DEBIAN)
        orig = g_strdup (SYSCONFDIR "/dhcp3/dhclient.conf");

This is my fault.  When I owned the dhcp package, I reorganized it to keep all dhclient and dhcpd configuration files in /etc/dhcp rather than /etc.  I did this to reduce clutter in /etc.  Problem is, I needed to teach NetworkManager about this new location on Fedora.

Dan, fix should be simple enough for NM.  In loader, I am writing out /etc/dhcp/dhclient-DEVICE.conf with a single line that is "send vendor-class-identifier ...;" based on what the user provides.  Actually, there's always a vendor class identifier even if the user doesn't override it.

It would be nice if we went back to legacy behavior with "anaconda" in the default. Then we'd only need dhcpclass= option to override and set something else.

The interface in anaconda isn't changing.  You will still just pass dhcpclass= on the boot line to override the vendor class identifier used during installation.  How that works underneath the installer is where the bug is, hence reassigning it to anaconda.

David, dhclient has afaik always used /etc/dhclient-ethX.conf.  Does anaconda use a different location?

    # allow users to use generic '/etc/dhcp/dhclient.conf' (as documented in manpage!)
    # if per-device file doesn't exist or is empty
    if [ -s /etc/dhclient-${DEVICE}.conf ]; then
       DHCLIENTCONF="-cf /etc/dhclient-${DEVICE}.conf";
    else
       DHCLIENTCONF='';
    fi;

is there some reason it's now /etc/dhcp/dhclient-<iface>.conf?

--- Additional comment from dcbw@redhat.com on 2010-06-23 18:29:48 EDT ---

Ok, is there any reason why the loader uses /etc/dhcp/dhclient-<iface>.conf while the rest of anaconda uses /etc/dhclient-<iface>.conf?

loader/net.c:        /* remove dhclient-DEVICE.conf if we have it */
loader/net.c:        if (asprintf(&ofile, "/etc/dhcp/dhclient-%s.conf", devs[i]->device) == -1) {
loader/net.c:    if (asprintf(&ofile, "/etc/dhcp/dhclient-%s.conf", iface->device) == -1) {
network.py:        # /etc/dhclient-DEVICE.conf
network.py:            dhclientfile = os.path.join("/etc/dhclient-%s.conf" % devName)
network.py:            self._copyFileToPath(dhclientfile, instPath)
packages.py:                glob.glob('/etc/dhclient-*.conf')

I can make NM check both locations I guess...

The dhcp package moved configuration files to /etc/dhcp at the end of 2008:

* Thu Dec 18 2008 David Cantrell <dcantrell@redhat.com> - 12:4.0.0-34
- Move /etc/dhclient.conf to /etc/dhcp/dhclient.conf
- Move /etc/dhcpd.conf to /etc/dhcp/dhcpd.conf

The incorrect references in anaconda need to be changed.
