Is it safe to have multiple clients share a NFS root on a pxe booted Linux

I have boot server that serves with PXE boot and rootdisk via NFS, the image will mount /run /var/log and /tmp as tmpfs and root / is mounted via NFS from the boot server.

Is it safe if I have multiple clients, that boot using the same image, and mount the same root filesystem? Will the system will work normally?
