It was documented for > ages, it is still documented in other BSDs. It has long ago been converted to a mount option instead of a tunefs command in NetBSD. My FreeBSD systems are patched that way since shortly after soft-updates was committed (long before it became available in NetBSD, IIRC); I have not checked whether they used the (very simple) patches I had posted at that time. Controlling soft-updates during mount has many advantages (not only if you decide to enable it on a root file-system that had been created without it) and no disadvantages. Regards, STefan
