Description Karlson2k 2020-08-27 14:14:09 UTC 
When booting with initramfs generated with genkernel-4.1.0, boot log always contains error:

Aug 27 16:30:50 MiniHTPC2 udevd[2262]: starting version 3.2.9
Aug 27 16:30:50 MiniHTPC2 udevd[2263]: starting eudev-3.2.9
Aug 27 16:30:50 MiniHTPC2 kernel: BTRFS: device label rootfs devid 1 transid 27027 /dev/nvme0n1p2 scanned by udevd (2270)
Aug 27 16:30:50 MiniHTPC2 udevd[2291]: failed to execute '/usr/lib/udev/${exec_prefix}/bin/udevadm' '${exec_prefix}/bin/udevadm trigger -s block -p ID_BTRFS_READY=0': No such file or directory

Root fs is btrfs.

emerge --info, the genkernel log, genkernel.conf could be useful, and your kernel command line should be helpful here.
Comment 2 Thomas Deutschmann (RETIRED) gentoo-dev 2020-08-27 15:33:40 UTC 
This sounds like bug 666892... I am wondering, the log is coming from host system -- in other words: Genkernel's initramfs is already finished.

Could you please post your

/lib/udev/rules.d/64-btrfs.rules

from real system?

No, it's not coming from host system.
I'm using systemd and it's loaded later than mentioned log line.
