Public bug reported:
https://launchpad.net/ubuntu/+source/systemd/259.5-0ubuntu1 recently migrated,
I see no bug reported and nothing in proposed about what I've seen on upgrade.
On upgrade I see (in red)
Setting up systemd (259.5-0ubuntu1) ...
...
fchownat() of /sys/kernel/security/tpm0/binary_bios_measurements failed:
Permission denied
fchownat() of /sys/kernel/security/ima/binary_runtime_measurements failed:
Permission denied
...
The two fchownat are red and the paths exist:
root@r-hwe:~# ll /sys/kernel/security/tpm0/binary_bios_measurements
/sys/kernel/security/ima/binary_runtime_measurements
lr--r--r-- 1 nobody nogroup 0 Feb 3 12:25
/sys/kernel/security/ima/binary_runtime_measurements@ ->
binary_runtime_measurements_sha1
-r--r----- 1 nobody nogroup 0 Feb 3 12:25
/sys/kernel/security/tpm0/binary_bios_measurements
Theory: this is a RR container on NN and hence the kernel might not have
that, but even then I'm unsure if fchownat would be happy through the
namespace isolation.
I guess the question is if this could be more graceful and less panic-
red in a container?
This could be in a library - I see the very same later again
