This is done in disk-detect so that the iSCSI LUNs are detected as disks (useful in case of no other disks in the system so the installer doesn't complain nor wait too long) and that any partman-related preseed options are not required and may be still available for the user. [Test Case] * linux package / kernel module in udeb: $ dpkg-deb -c scsi-modules_*.udeb | grep iscsi_ibft.ko Check the module loads in the installer environment. See comment with example for disco. * d-i/hw-detect/partman-iscsi package: See comments 11, 12, 13. [Regression Potential] * linux package: low, the kernel module is not loaded by default, and only checks whether iBFT information is present in firmware, then exposes that in sysfs in read-only mode. * d-i/hw-detect/partman-iscsi: - d-i: kernel version update to include iscsi_ibft module, based on kernel released to -updates plus one week monitoring bug reports -- it should be OK. Tested on amd64/i386/arm64/ppc64el on QEMU, plus amd64 on baremetal -- see comment 11. - hw-detect: low, the changes are enabled by a preseed option. see comment 12. - partman-iscsi: low, simple changes, plus one fix that has been tested in detail, and falls back to previous behavior if it fails. see comment 13. [Other Info] * This has been verified both by the developer with a simple iSCSI iBFT environment (2 VMs: iSCSI target & initiator with UEFI+iPXE) and by an user with system/firmware that supports iBFT for iSCSI.
