Description goatshit54108 2020-06-04 16:09:55 UTC 
`newfs -R` has the purpose of enforcing reproducible output, i.e. to be independent of time or random seeds. However, it is incomplete, because sbput(3) writes a fresh time() sample into the `struct fs` variable: see ffs_sbput() in sys/ufs/ffs/ffs_subr.c.
