[ Reason ]
xfs_scrub_fail email reporting fails, which is documented as #1116595.
This is specific to a mail setup that I do not use.
[ Impact ]
"Permission denied" entries spam the system logs:
postfix/postdrop[37291]: warning: mail_queue_enter: create file maildrop/480926.37291: Permission denied
This is due to systemd sandboxing features in xfs_scrub_all_fail.service
not aligning with the sendmail setup.
[ Tests ]
Check the xfs_scrub_all_fail.service to run properly.
I do not have the time to replicate the bug-described setup. Sorry.
[ Risks ]
This is taking away sandboxing features that are too strict for this
type of service.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in stable
[x] the issue is verified as fixed in unstable
[ Changes ]
New patch changes one file and comes from upstream.
This removes systemd sandboxing features that are too strict,
especially CapabilityBoundingSet= and NoNewPrivileges=true.
[ Other info ]
The service can just be disabled (the feature does not work with trixie
anyway) but people really want a stable update.
