Dear systemd folks,
Debian uses a shell script as `/init` in initrd, and I like to extend that,
to set the time stamps for the initrd execution.
This is part of the data that is serialized during the transition from
the systemd instance in the initrd to the systemd instance on the
host. The serialization is internal to systemd, and this is unlikely
to change, as it contains numerous bits of information that are
fragile and sensitive as the serialization really contains the full
service manager state with all its units and so on.
Is it possible to set that value from a shell script? If yes, could you
please tell me how?
It's not, and quite frankly I am not enthusiastic about the idea to
make this configurable...
At one point, I was considering to serialize just enough data to add
these in the initramfs-tools (and/or systemd) as Debian specific
patches to start supporting these measurements.
And have a distro patch in systemd to read these measurements from a
separately serialized file on boot-up.
Yeah, that wolud be good to have. Do you know, if there are feature
requests for these already?
Also, there are bootloader measurements, that I think we do not
receive either from grub.
With Ubuntu 18.04 on a TUXEDO Book BU1406 with Ubuntu 18.04, UEFI
firmware and GRUB, I get the output below.
Startup finished in 5.793s (firmware) + 3.339s (loader) + 7.002s (kernel) +
8.107s (userspace) = 24.242s
Kind regards,
Paul
