In general softupdates will make the entire filesystem safer. : :Does it make sense to use softupdates on file systems like / and :/usr which have little file creation/removal? : :Greg I have had softupdates turned on for all of my mount points for over a year. For /, the only issue is that if you have too small a root parition a 'make installworld' may run the filesystem out of space faster then softupdates can free the blocks. My root partition is always 128M for that reason (and also so I can throw a few kernel.debug images in there). My recommendation is to turn softupdates on for everything you have, and for us to make it a newfs default as well. At least in -stable. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
