Package: netcfg
Version: 1.46
Severity: wishlist
Tags: lenny

I have a situation where I want to use a single, custom debian installer initrd, but want to preseed network configuration differences between production cdrom and development netboot installers.

The systems in the field should not have networking enabled at all. With the stock Lenny installer, on systems with wireless cards and no proprietary firmware blobs, you get scary red error screens during the install complaining about network errors. If you add the firmware blobs to the d-i just to shut up the errors, and if the hardware switch is turned off, you again get scary red error screens about network errors.

I don't want *any* networking on the cdrom installs, but I also want to use a consistent initrd between development and production to avoid possible bugs from using different installers.

Enter this patch. It allows me to optionally disable network configuration completely via preseed on the cdrom install, but leaves the default to enabled for netboot. The attached patch may be a horrible, ugly hack based on the d-i design, but it works for me. If you don't like this patch, can you add a similar capability going forward?

 netcfg (1.52) unstable; urgency=low
   [ Aurelien Jarno ]
   * Loopback network interface name is lo on GNU/Linux and lo0 on
     GNU/kFreeBSD; generalize it with a macro.
   * Build the netcfg binary package on sh4.
   [ Otavio Salvador ]
   * Add support to disable network configuration using preseeding in
     netcfg/enable template. Thanks to Anthony L. Awtrey
     <tony@awtrey.com> for the patch. Closes: #538265
   [ Colin Watson ]
   * On Linux, feed the output of 'ip addr show' into /dev/random after the
     network is up to improve entropy. Idea picked up from Theodore Y. Ts'o,
   * Upgrade to debhelper v7.
   * Tell dhclient to wait for netcfg/dhcp_timeout seconds before exiting
     (closes: #566006, LP: #315231).
   [ Otavio Salvador ]
   * Use busybox' udhcpc by default but kfreebsd-amd64 and kfreebsd-i386
     since they lack support in busybox at this moment.
   [ Frans Pop ]
   * Remove no longer needed Lintian override for missing Standards-
     Version field.
   * Disable wireless support for s390.
   * Fix FTBS on s390 caused by upgrade to debhelper v7.
   * Drop support for the discontinued lpia architecture.
   * Improve test for presence of dhcp/dhcp3.
   * Don't ship unnecessary/unused dhcp directories.
