View Full Version : Does relatime mount option interfere with popularity contest data?

I like to participate in the data collection provided by Debian's popularity contest, which I allow during setup.

One thing I also like to do is force the filesystem not to write timestamps to files marked read-only by using a mount point option in /etc/fstab.

Formerly, I used to use noatime in my fstab, but that made the data submitted from my box useless for the popularity-contest tally package.

Like Fedora and now Ubuntu, relatime is another option, but currently is not enabled by default with Lenny-Testing. I do it manually by reconfiguring my /etc/fstab. Example:

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/sda6 / ext3 relatime,errors=remount-ro 0 1
/dev/sda7 none swap sw 0 0
/dev/hda /media/cdrom0 udf,iso9660 user,noauto 0 0

I haven't been able to confirm if using relatime, in it's current Lenny-Testing incarnation, will interfere with providing accurate results to PopCon. I know noatime does, but I just don't want to submit bad info if relatime isn't prime time yet.

As far as I know relatime should be fine. My understanding is that relatime is now updating atime as well. At least something like that was discussed on the kernel list about a year ago.

btw, during install you can select mount options at the partitioning stage so no need to do change to relatime manually unless you wish to do so.

Ah, nice to know about being able to choose mount options at partition time. I'll have to look for it again, as I just installed Lenny on my AMD/64 desktop before reading this! I'm blown away.

Up next is the laptop, so I'll look for the mount option when I do that one.

Thanks for the tip!
