System cannot boot when usr is a separate file system with latest systemd-219-78.el7_9.8

Issue

What were you trying to do that didn't work? All systems configured with a dedicated /usr cannot boot anymore after updating systemd to systemd-219-78.el7_9.8. Root cause is a bad mount unit generation done by systemd-fstab-generator: sysroot-sysroot-usr.mount gets generated instead of sysroot-usr.mount. Mounting /sysroot/sysroot/usr... [FAILED] Failed to mount /sysroot/sysroot/usr. See 'systemctl status sysroot-sysroot-usr.mount' for details. [DEPEND] Dependency failed for Initrd File Systems. : [ 1.781938] systemd[1]: No /sbin/init, trying fallback [ 1.782970] systemd[1]: Failed to execute /bin/sh, giving up: No such file or directory :/# cat /run/systemd/generator/sysroot-sysroot-usr.mount # Automatically generated by systemd-fstab-generator [Unit] SourcePath=/sysroot/etc/fstab Documentation=man:fstab(5) man:systemd-fstab-generator(8) Before=initrd-fs.target [Mount] What=/dev/mapper/rhel-usr # Canonicalized from /sysroot/usr Where=/sysroot/sysroot/usr Type=xfs This seems to have been introduced by Patch 0853-fstab-generator-Chase-symlinks-where-possible-6293.patch.
