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:

 #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.

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

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?

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> - 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.

And we  need to  make sure that initscripts are updated too.

Reassigning to David as he is fixing this bug in rhel6.

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
