Thanks everyone, I've nailed it \o/ A more detailed story follows. After taking the approach of offloading / and /usr checks to Dracut I've disabled fsck for those partitions in /etc/fstab so OpenRC fsck wouldn't attempt to check /usr (and fail) by setting passno (the last column to 0). It turned out that Dracut honours fstab for fsck too (root get special treatment and is checked anyways). After enabling fsck in fstab for / and /usr Dracut started to check /usr - a small win already. No the only thing left to do was to _not_ check / and /usr by the init fsck which was natural to do by setting fsck_passno=">1" in /etc/conf.d/fsck.
Now all the filesystems are checked during the boot: the ones having passno 1 (root and /usr) by the initramfs and passno 2 (/var, /home, /data) by the init. The relevant excerpts from the final configuration are below. /etc/fstab: /dev/MacVg/gentoo-root / ext4 defaults 0 1 /dev/MacVg/gentoo-usr /usr ext4 defaults 0 1 /dev/MacVg/gentoo-var /var ext4 nodev,nosuid 0 2 /dev/MacVg/gentoo-home /home ext4 nodev,nosuid 0 2 /dev/MacVg/data /data ext4 nodev,nosuid,noexec 0 2 /etc/dracut.conf: hostonly="yes" use_fstab="yes" no_fsck="no" Note that the two latter Dracut options are not required and applied by default in my installation but showing explicitly what configuration is used. /etc/conf.d/fsck: fsck_passno=">1" As can be seen from logs / and /usr are checked by Dracut and /var, /home and /data by OpenRC. /var/log/dmesg: [ 2.607796] dracut: luksOpen /dev/sdb3 luks-2acb7668-fff1-492d-b46e-f05ead26d153 [ 5.930575] random: crng init done [ 11.017574] dracut: Scanning devices dm-0 for LVM logical volumes MacVg/swap MacVg/gentoo-root MacVg/gentoo-usr [ 11.028712] dracut: inactive '/dev/MacVg/arch-root' [10.00 GiB] inherit [ 11.031019] dracut: inactive '/dev/MacVg/arch-var' [6.00 GiB] inherit [ 11.033121] dracut: inactive '/dev/MacVg/swap' [8.00 GiB] inherit [ 11.035193] dracut: inactive '/dev/MacVg/arch-home' [6.00 GiB] inherit [ 11.037305] dracut: inactive '/dev/MacVg/data' [48.00 GiB] inherit [ 11.039686] dracut: inactive '/dev/MacVg/gentoo-root' [1.00 GiB] inherit [ 11.042072] dracut: inactive '/dev/MacVg/gentoo-var' [1.00 GiB] inherit [ 11.044452] dracut: inactive '/dev/MacVg/gentoo-home' [2.00 GiB] inherit [ 11.046791] dracut: inactive '/dev/MacVg/gentoo-usr' [12.00 GiB] inherit [ 11.131447] dracut: Scanning devices dm-0 for LVM volume groups MacVg [ 11.137382] dracut: Reading all physical volumes.

S. A bonus point is I no longer have to patch genkernel to support custom keymaps and fonts. --- Andrew
