[Pkg-utopia-maintainers] Bug#1043177: dbus-broker: kernel: memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL, pid=756 'dbus-broker-lau'

[Paul Wise]

Package: dbus-broker
Version: 33-1
Severity: normal
Usertags: warnings

I noticed that during boot the Linux kernel version 6.4.4 complains
about how dbus-broker-launch uses memfd_create, it should use one of
the MFD_EXEC nor MFD_NOEXEC_SEAL options. No reason is given though.
