In theory, you may just loose a little space over time. I've also read Terry Lambert's post (SU/LFS/JFS) warning against using SU for fast failure recovery (but may be comfortable with the risks for now, given the effort in porting LFS or a JFS to FreeBSD -- i.e. some -vs- none). My question: Is anyone running a system using soft updates and NOT fscking after crashes? Is it even reasonable in practice? Mount refuses to mount a filesystem that isn't marked clean. If anyone is doing the above, what (non-fsck) mechanism do you use to mark the filesystems clean? I've been experimenting with 4.2-RELEASE but have current and stable available as well.
