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.
