Change subject: autoinstall: set get_domain=unassigned on jessie ...................................................................... autoinstall: set get_domain=unassigned on jessie d-i's netcfg has a bug where the DHCP domain name option gets ignored for preseeding purposes and manual input is required. I debugged this extensively and filled it as https://bugs.debian.org/772523. As we run the installer with priority=high (the default), meaning that we get prompted for >= high questions, this breaks automated installs in Debian. The bug exists in Ubuntu as well, but Ubuntu has a custom patch on top of netcfg that downgrades that question to priority=medium. The reason for that is unknown, as in a typical Ubuntu fashion, the custom patch is undocumented in the Ubuntu source and was never forwarded to Debian along with a reational. It's possible it's a wrong fix for the bug above (as the domain is prefilled). Besides pushing for a fix in time for jessie, we have the following options for a workaround: 1) Set d-i to priority=critical. This may be a good idea anyway but as this touches far more that netcfg, it's not a great workaround. 2) Remove "option domain-name" from our DHCP config; d-i would resort to the hostname found in the FQDN and the bug would not manifest. This is not a very elegant solution. 3) Bundle the isc-dhcp-client udeb into a gzipped cpio and append it to jessie's initrd. I approached this solution but it got messy real quick (multiple library udeb dependencies, glibc incompatibilities etc.) 4) Trick d-i by setting netcfg/get_domain to "unassigned" (or any other value) in the kernel command-prompt, similar to how we set netcfg/get_hostname to "unassigned" too. This affects only the bootstrap phase of the installer anyway, as immediately after netcfg comes preseeding and we preseed domain-name anyway, under our subnets/ configuration. This implements solution (4). As the bug doesn't manifest in Ubuntu (as explained above), this touches only the jessie config.
