** Description changed: [ Impact ] * when using Subiquity's autoinstall feature, once can use "match" directives at the storage->layout level to find the right drive. However, the match directives where silently ignored when using mode: use_gap. * This makes it difficult for the OEM team to install to the installation media. [ Test Plan ] == Target issue test plan == 1. Prepare a VM with 2 disks with identical size, 48G for testing purposes, (we call them disk A and B) 2. Boot into a live environment, and create 2 partitions on disk A: - a 512M EFI System Partition - a 12G FAT32 partition for "reset partition" leave the remainings of disk A, and the whole disk B unallocated. 3. Copy contents in the Ubuntu installer ISO into the "reset partition" 4. Place an autoinstall.yaml file in the root of reset partition, with the following contents: #cloud-config autoinstall: version: 1 storage: layout: name: direct mode: use_gap match: install-media: true identity: hostname: ubuntu username: ubuntu password: "$6$exDY1mhS4KUYCE/2$zmn9ToZwTKLhCw.b4/b.ZRTIZM30JZ4QrOQ2aOXJ8yk96xpcCof0kxKwuX1kqLG/ygbJ1f8wxED22bTL4F46P0" # (password is ubuntu, copied from Autoinstall Quickstart howto guide) - 5. Reboot into Reset Partition and complete the installation + 5. Change the boot/grub/grub.cfg in the reset partition, and add + "nopersistent" in the kernel command line, this is to not let casper + expand the disk for the installer environment. - 6. Check the system is installed in the disk A instead of disk B + 6. Reboot into Reset Partition and complete the installation + + 7. Check the system is installed in the disk A instead of disk B == Regression test plan == 1. Install a Ubuntu system by any means 2. Use the subiquity under test, and install into the same disk by shrinking the partition size of the previous installation. 3. Both OSes should be accessible through GRUB menu. [ Where problems could occur ] Regressions caused the normal Ubuntu installation unable to continue. [ Other info ] The change to merge is https://github.com/canonical/subiquity/pull/2083 [ Original description ] We found a problem that the following autoinstall config: storage: layout: name: direct mode: use_gap match: install-media: true does not actually match install-media, because use_gap does not use match directive to filter disks before finding a largest gap, according to the code in the below link: https://github.com/canonical/subiquity/blob/6727905effc4abc2d96c96986600efe392e3b7b6/subiquity/server/controllers/filesystem.py#L1614 Internal reference: NANTOU-470
