(/usr, /var, /usr/home, etc) In file /usr/src/release/sysinstall/label.c, function new_part(): ret->soft =3D strcmp(mpoint, "/") ? 1 : 0; Basically, softupdates are enabled for everything *but* the root partition. (To Aur=E9lien) The real reason (as I understand it from -stable discussion) root doesn't have softupdates turned on by default is that during installation, the root system can fill up since softupdates waits from releasing space from temporary files. I personally had a problem with running a recent 4.X release install and turning on softupdates for root ('/') without thinking about it and having the system say that there was no space on the drive during installation. Outside of the warnings regarding IDE and write-caching, you can turn on softupdates for root after installation with the tunefs command. (You'll need to do it from single-user) Jaime Bozza -----Original Message----- From: owner-freebsd-stable@FreeBSD.ORG [mailto:owner-freebsd-stable@FreeBSD.ORG] On Behalf Of Michael Lucas Sent: Monday, August 19, 2002 9:55 AM To: Aur=E9lien Nephtali Cc: stable@FreeBSD.ORG Subject: Re: root (/) not soft-updates by default ? Hello, Soft updates does not work well with IDE controllers with write caching enabled; you can cause data loss. Most IDE controllers ship with write caching enabled. We won't, by default, ship systems which have an unacceptable risk of data loss. :-) On Mon, Aug 19, 2002 at 04:49:28PM +0200, Aur=E9lien Nephtali wrote: > Hello, >=20 > What is the reason that the mount point (by default, /) hasn't the flag > for soft-updates by default (during the installation), can I set it > without data lost ? >=20 > -- Aur=E9lien To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
