** Also affects: linux-kvm (Ubuntu)
Importance: Undecided
Status: New
** Description changed:
+ Note: this bug touches on multiple packages:
+ - autopkgtest-cloud: merge request open to install 'modules-extra' package
+ - systemd: update autopkgtest to skip test if scsi_debug module isn't
available (SRU template below is for this change)
+ - linux-kvm: has CONFIG_SCSI_DEBUG unset, but would be good to have
scsi_debug module built for this kernel
+
+ [SRU template for systemd]
+
[impact]
the 'storage' autopkgtest requires the 'scsi_debug' module, and if it
can't load it (and it's not built-in), the test fails. On some custom
kernels, this module is included in the new 'linux-modules-extra-*' deb
which isn't installed by default, so the test always fails when doing a
reverse-dep autopkgtest using such a kernel's meta pkg.
Additionally, some custom kernels, like linux-kvm, have SCSI_DEBUG
disabled entirely; for those kernels, it will never be possible to load
the scsi_debug module and the test should be skipped.
[test case]
run the 'storage' autopkgtest with a custom kernel that doesn't provide
the scsi_debug module in the standard linux-modules deb, or check the
autopkgtest.u.c history, for example:
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac
/autopkgtest-focal/focal/amd64/s/systemd/20191209_150835_237a5@/log.gz
[regression potential]
as this modifies one of the autopkgtest --setup-commands, a regression
would most likely cause immediate test failure due to failing to install
the proper linux-* debs.
For the systemd 'storage' test change, this only skips the test if the
scsi_debug module can't be loaded (and isn't already present, i.e.
loaded or built-in). Any regression potential from that is low, but
likely would involve incorrect test skips and/or missing valid problems
due to skipping the test.
[scope]
systemd in all releases needs to have its 'storage' test updated
