fai-quickstart depends on EOL and not longer supported isc-dhcp.  See
https://bugs.debian.org/1106121.

I wonder why you filed a serious bug report so late in the release process.
We all know the EOL of isc-dhcp, but what alternatives should be used,
without the need of major changes?

I guess we have other packages that are stalled upstream, but that
does not mean, that we must remove them from testing.

Please provide an alternative we can use.

Hi,

this bug also affects more packages that are not in the reverse dependency.
Several packages call dhclient and sometimes with options that are
only available for the isc dhcp client, like -lf ,-pf, -sf

Following packages may be affected by the removal of isc-dhcp from
trixie, because I couldn't find code that supports another dhcp
client/server in those packages:

- chkrootkit_0.58b-4/debian/tests/control
- chrony_4.6.1-2/debian/tests/time-sources-from-dhcp-servers
- cowdancer_0.90/initrd/quick-arm-init.sh
- debian-edu-config_2.12.46/share/debian-edu-config/isc-dhcp-server.service
- debian-edu-router_2.13.0~beta7/fai/config/hooks/instsoft.GATEWAY.sh
- dracut_107-1/modules.d/35network-legacy/module-setup.sh
- firejail_0.9.74-1/src/firejail/dhcp.c
- guix_1.4.0-9/gnu/services/networking.scm
- ifupdown2 in ifupdownaddons/dhclient.py
- ikvswitch_1.0.4/usr/bin/ikvswitch-setup
- madwimax_0.1.1-4/scripts/events/event.sh.generic.in
- octavia_16.0.0-1/octavia/amphorae/backends/utils/interface.py
- python-isc-dhcp-leases_0.10.0-3/isc_dhcp_leases/iscdhcpleases.py
- runit-services_0.9.1/debian/runit-services.runit
- sitesummary_0.1.60/sitesummary-nodes


- debian-edu_2.12.17/debian/control: recommends isc-dhcp-server

These packages use the network-legacy module of dracut which only
supports isc-dhclient:
- kiwi_10.2.22-1/test/data/description.buildservice/appliance.kiwi
- fai_6.4.3/bin/fai-make-nfsroot

The last message
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1106124#19
should go to #1106121. I will resent this. Please ignore this info for
the package fai-quickstart.

I've asked on the FAI mailing list about the usage of ISC dhcp and got
a few answers:

https://lists.uni-koeln.de/pipermail/linux-fai/2025-May/thread.html

Only one started the very slow the migration to dnsmasq. Most are
afraid of the complexity of KEA and still use ISC dhcp server.
But they know that they have to migrate to another tool in the
future.

We believe that the bug you reported is fixed in the latest version of
fai, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1106124@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
