There was a bug in FreeBSD 4.0-RELEASE's tunefs (since fixed in 4.0-STABLE), which prevented the use of tunefs on filesystems mounted for writing. If you track 4.0_STABLE, this problem should go away. If not, you'll have to boot off a floppy to tune your root filesystem. Having said that, I personally discourage people from enabling soft updates on the root filesystem. Very few folks do enough writing to the root filesystem to justify this. The two cases where people think they need this are 1) /tmp is not its own filesystem Solution: mount /tmp in mfs(8) or an md (undocumented). 2) The filesystem is not partitioned; there is only the root filesystem. Solution: usually, don't do this. :-) In the second case, wanting to enable soft updates on the root filesystem makes sense. However, in the case of a normal, partitioned configuration, the root filesystem is usually small and can "run out of space" during a ``make world''. Ciao, Sheldon.
