Expected behaviour you didn't see

This started happening with the v260 update.

This seems to only happen on the PPC64LE runner from OSUOSL and I haven't managed to reproduce locally when cross-building ppc64 on my x86_64 local PC.

Any idea what Protocol driver not attached means here? The generation was previously working on the same runner with v259, #40285 added logs/warns but I'm not sure why it is failing to open the directory now.

Unexpected behaviour you saw

hwdb database fails to generate.

Steps to reproduce the problem

N/A happens only in the runner

Additional program output to the terminal or log subsystem illustrating the issue

N/A

Please run with SYSTEMD_LOG_LEVEL=debug to get additional logs

[poettering]

what kernel is this?

[poettering]

STATX_MNT_ID is available since kernel 5.10, which is our minimum baseline. My decuated guess: your kernel is older?

[bbhtt]

The ppc64le runner has Linux buildbox 4.18.0-553.109.1.el8_10.ppc64le #1 SMP Mon Mar 2 13:53:18 UTC 2026 ppc64le GNU/Linux

Did the baseline get bumped in 260? This seems to be working with 259. If so we need to contact OSUOSL and ask them to upgrade the kernel.

[poettering]

We announce baseline bumps in NEWS. You'll find 5.10 being the baseline since v259.

The last version of systemd that had 4.18 above its baseline was v257.

Closing.
