while running meson, the build breaks with Program missing_syscalls.py found: YES (/usr/bin/python3.11 /tmp/portage/sys-apps/systemd-utils-254.10-r1/work/systemd-stable-254.10/src/basic/missing_syscalls.py) Program check-filesystems.sh found: YES (/tmp/portage/sys-apps/systemd-utils-254.10-r1/work/systemd-stable-254.10/src/basic/check-filesystems.sh) ../systemd-stable-254.10/src/basic/meson.build:234:8: ERROR: Problem encountered: Unknown filesystems defined in kernel headers: Filesystem found in kernel header but not in filesystems-gperf.gperf: PID_FS_MAGIC
Need emerge --info's output to confirm linux-headers version, but I assume you're mixing ~testing linux-headers-6.9 with stable systemd-utils. Aka this is already fixed in ~testing systemd-utils-254.12
(also, rather than using systemd-utils-254.12, I'd recommend using stable linux-headers)
Full build.log, meson-log.txt, and emerge --info please. It's probably new linux-headers with <systemd{,-utils}-255.
Ah, jinx.
