With stabilization of genkernel-4.3.16, my system was upgraded from genkernel-4.3.10. It looks like that upgrade included an upgrade of lvm2 used by genkernel. The new lvm2 seems to include a udev rule that causes errors when booting on system that doesn't have systemd: # dmesg ... [ 28.325386] udevd[2061]: failed to execute '/usr/bin/systemd-run' '/usr/bin/systemd-run --no-block --property DefaultDependencies=no --unit lvm-activate-nvme /usr/sbin/lvm vgchange -aay --autoactivation event nvme': No such file or directory After doing some digging around I found that the udev rule that is trying to run systemd-run was built into the initramfs at /usr/lib/udev/rules.d/69-dm-lvm.rules. That file is part of LVM2. The ebuild for sys-fs/lvm2 includes a patch that replaces that rule for systems that don't have systemd. Looks like genkernel probably needs to apply a corresponding patch when building lvm2 (at least when building on a system that doesn't have systemd).

I have same issue on my Gentto: installed is sys-kernel/genkernel-4.3.16-r2 problem is not only same error messages: [ 3.979142] udevd[2401]: failed to execute '/usr/bin/systemd-run' '/usr/bin/systemd-run --no-block --property DefaultDependencies=no --unit lvm-activate-system /usr/sbin/lvm vgchange -aay --autoactivation event system': No such file or directory [ 4.002315] udevd[2402]: failed to execute '/usr/bin/systemd-run' '/usr/bin/systemd-run --no-block --property DefaultDependencies=no --unit lvm-activate-data02 /usr/sbin/lvm vgchange -aay --autoactivation event data02': No such file or directory [ 4.002376] udevd[2403]: failed to execute '/usr/bin/systemd-run' '/usr/bin/systemd-run --no-block --property DefaultDependencies=no --unit lvm-activate-kvm-storage /usr/sbin/lvm vgchange -aay --autoactivation event kvm-storage': No such file or directory [ 4.002417] udevd[2404]: failed to execute '/usr/bin/systemd-run' '/usr/bin/systemd-run --no-block --property DefaultDependencies=no --unit lvm-activate-data01 /usr/sbin/lvm vgchange -aay --autoactivation event data01': No such file or directory Main problem is that root and usr is mounted not as lvm devices but as dm-5 and dm-8.

I don't see any edit button there for modify of my comment: I forgot write that i use systemd. I tried add to kernel image missing command /usr/bin/systemd-run and dependence(libraries) via genkernel overlay, but problem persist. Root and usr lvm volumes are mounted incorrect ad dm-X devices.
I had the same situation as the bug reporter. I updated from 4.3.16 -> 4.3.16-r2 and *that* error is gone but there is still something strange about udev. Now im getting this error from udev: failed to execute '/usr/lib/udev/dmi_memory_id' 'dmi_memory_id': No such file or directory Full log: > daemon:err : 2024-11-28T19:43:31,175411+01:00 udevd[1417]: failed to execute '/usr/lib/udev/dmi_memory_id' 'dmi_memory_id': No such file or directory > daemon:err : 2024-11-28T19:43:32,657565+01:00 udevd[1429]: failed to execute '/usr/lib/udev/fido_id' 'fido_id': No such file or directory > <SNIP: 7 same lines> > kern :warn : 2024-11-28T19:43:45,693212+01:00 printk: udevd: 4 output lines suppressed due to ratelimiting On my system I do *not* have dmi_memory_id but I *do* have fido_id.

The new patch files/lvm2-2.03.20-dm_lvm_rules_no_systemd.patch causes the new problem: https://bugs.gentoo.org/947185 (solution included).
