Attached the uploaded diff for jammy. Besides the few lines changed in
scripts/functions I backported the improvements of the autopkgtest to
increase the test coverage and to test on all architectures. See
https://code.launchpad.net/~ubuntu-core-dev/ubuntu/+source/initramfs-
tools/+git/initramfs-tools/+ref/ubuntu/jammy for the individual commits
for details. I tested the autopkgtest changes in my PPA.
** Description changed:
+ [ Impact ]
+
+ * MAAS cannot PXE-boot a machine that has iSCSI disks
+
+ * Focal is the default Ubuntu distribution deployed by MAAS, so we should
+ back-port this to ensure it works out-of-the-box.
+
+ [ Test Plan ]
+
+ * reproducing this issue requires a machine with iSCSI disks (Cisco UCS
Manager
+ in the original report), and a MAAS controller (3.4 or better)
+
+ * the issue can be observed by simply enlisting the machine in MAAS. It will
+ fail to boot due to the missing BOOTIF configuration.
+
+ [ Where problems could occur ]
+
+ * the problematic code was an attempt to fix LP#2037202, so we should watch
out
+ for regressions.
+
+ [ Original report ]
+
we have a bad interaction between initramfs-tools and open-iscsi,
resulting in the boot interface not being configured.
when the iscsi has a static address, the script `local-top/iscsi` from
open-iscsi creates a /run/net-$DEVICE.conf file for the iscsi interface.
The existence of this file makes configure_networking() skip configuring
the BOOTIF later due to this code in `scripts/functions`:
- for x in /run/net-"${DEVICE}".conf /run/net-*.conf ; do
- if [ -e "$x" ]; then
- IP=done
- break
- fi
- done
+ for x in /run/net-"${DEVICE}".conf /run/net-*.conf ; do
+ if [ -e "$x" ]; then
+ IP=done
+ break
+ fi
+ done
