** Description changed:
[Impact]
In debian/tests/run-image we instantiate an image with 512Mb of ram, but
recent jammy/lunar 6.2 kernels need more than that.
Example of a test failure:
https://autopkgtest.ubuntu.com/results/autopkgtest-lunar/lunar/amd64/i/initramfs-tools/20230619_135049_ab1cb@/log.gz
'net' test fails with a kernel panic due to out-of-memory.
+ It also relies on an existing and working cloud image. If the cloud
+ image is not available, the test will silently succeed.
+
[Fix]
- Increase the size to 1Gb.
+ The net autopkgtest was ported to the common test framework in
+ initramfs-tools 0.142ubuntu3. This makes the test more robust by relying
+ on the minimum needed for the integration test.
[Test Plan]
+
+ Check that the autopkgtest succeed or test it manually:
+
1. Download a lunar image:
$ autopkgtest-buildvm-ubuntu-cloud -v -a amd64 -r lunar
2. Run autotestpkg tests from initramfs-tools package. The "net" test is the
one that depends on the image instantiated by 'run-image'. The testcase should
complete successfully without the kernel panic.
$ autopkgtest initramfs-tools -- qemu autopkgtest-lunar-amd64.img
[Where problems could occur]
The usage of a larger image for the tests could fail if the the test system
is low on ram size.
-
- Notes:
- It seems Mantic already uses 1G, so nothing has to be changed there. I also
tested it locally and I confirm it works as expected there.
