X-Newsgroups: list.freebsd-hackers User-Agent: tin/1.5.4-20000523 ("1959") (UNIX) (FreeBSD/4.6-STABLE (i386)) MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 8bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hi, The mount(8) manpage doesn't mention it, so I assume that there is no such thing as a "nomtime" option (analogous to the "noatime" option) to prevent the mtimes of inodes from being updated for each write access. But maybe is there some other way to achieve that? For example, updating of mtimes is not neccessary on a file system that contains a news spool, or the content of a web cache, or similar transient data. Disabling those updates might prevent quite some superfluous overhead. I'm tempted to try implementing "nomtime" myself, but I would prefer hearing some opinions first before wasting time on something completely stupid. :-) Regards Oliver -- Oliver Fromme, secnetix GmbH & Co KG, Oettingenstr. 2, 80538 München Any opinions expressed in this message may be personal to the author and may not necessarily reflect the opinions of secnetix in any way.
