Package: debian-installer Severity: normal Dear Maintainer,
when DHCP server is configured to send bootfile option with iPXE script then debian-installer fails with following "red" error: [!!] Download debconf preconfiguration file Failed to process the preconfiguration file The installer failed to process the preconfiguration file from <bootfile>. The file may be corrupt. (where <bootfile> is value of that DHCP option) It looks like debian-installer expects that DHCP bootfile option will contains correct preseed file. And if that DHCP option contains not Debian preseed file, then it show above "red" error message. On the other hand, DHCP bootfile option is used for iPXE to specify boot script too (can be detected by first shebang '#!ipxe' line). Debian installer should not try to always process DHCP bootfile option as it does not have to contain Debian preseed file... Due to this bug booting Debian installer from iPXE setup is broken. On http://boot.oskarcz.net/ is running such iPXE setup. You can easily reproduce this problem by starting iPXE in qemu and trying to start installation of Debian. qemu-system-x86_64 -net nic -net user,bootfile=http://boot.oskarcz.net/
