To: openembedded-devel
In most machines' fstabs rootfs mounted with 'defaults' option.
This implies that atime logging is on - i.e. on every read from
filesystem kernel writes atime stamp to files' metadata.
Here in embedded world, where rootfs is usually stored on some
kind of flash (internal NAND/NOR, or external SD/MMC/CF card)
it is a real problem, because higher number of writes causes
flash wearing, higher system load and higher chance of filesystem
corruption.
Fix it by adding noatime to rootfs mount options in fstab.

Good idea. On Zaurus it even prevents regular hard disc waking up while
executing scripts and significantly increases speed of writing of large
amount of small files.
Patching of udev mount.sh script would be useful as well.

If there's no objections, can somebody apply this?
(hint: I don't have a commit rights)
I can send updated patch if needed - though changing 'packages' to
'recipes' with sed shouldn't be too hard:
sed -i 's:a/packages/:a/recipes/:g' *.patch
sed -i 's:b/packages/:b/recipes/:g' *.patch

Yes. I'll try too look into this.

Isn't 'relatime' a better option?

Maybe yes, but we need more care in this case, because relatime has
been introduced in 2.6.20 [1], and there's still can be machines using
older kernels (judging solely by looking at the recipes in recipes/linux).
I fear that we may break booting on these machines by passing
unsupported option to mount.

I belive that if those machines still uses old kernels they have the
responsability to deal with those things; besides that it is very
common for machines to provide custom fstab files so it won't
hurt to put a specific one to workaround it if required.

In case with default fstab - yes, probably you are right, since it can
be easily overrided by custom version for specific machine/distro.
But we need to carefully check which of the pre-existing
machine-specific fstabs can be modified to use relatime.
I've made some investigations by running this script:
ls recipes/base-files/base-files/*/fstab | cut -d/ -f4 | \
while read MACHINE ; do echo $MACHINE; \
bitbake -c setscene -n -vv virtual/kernel | grep setscene ; done
and then reformatting output by hand. Here's the results
(checked with Angstrom distro):

As you can see there's still a lot of machines with 2.6.19, 2.6.16 and
even 2.4 kernels.
Anyway, I've redone patch by leaving out fstab for machines with
kernel <2.6.20 and also non-machine-fstabs (probably distro-specific -
openmn, openprotium, slugos, armzone-qt2410).
I'll send current version in following mail.

* [PATCH] base-files: add relatime to rootfs mount options

In most machines' fstabs rootfs mounted with 'defaults' option.
This implies that atime logging is on - i.e. on every read from
filesystem kernel writes atime stamp to files' metadata.
Here in embedded world, where rootfs is usually stored on some
kind of flash (internal NAND/NOR, or external SD/MMC/CF card)
it is a real problem, because higher number of writes causes
flash wearing, higher system load and higher chance of filesystem
corruption.
Fix it by adding relatime to rootfs mount options.
NOTE: since relatime option only available on 2.6.20+ kernels,
following fstabs weren't touched, as these machines seem to use
older kernels (kernel versions checked against Angstrom distro, other
distros may vary):
amsdelta linux-amsdelta-2.6_2.6.16-omap2.bb
epia linux-epia_2.6.19.2.bb
h6300 linux-h6300-omap1_2.6.16.16.bb
jornada7xx linux-jlime-jornada7xx_2.6.19rc6.bb
mtx-1 linux-mtx-1_2.4.27.bb
mtx-2 linux-mtx-2_2.4.27.bb
netbook-pro netbook-pro-kernel_2.6.17.bb
nokia770 linux-nokia800_2.6.18-osso40.bb
wrt54 linux-wrt_2.4.30.bb
xxs1500 linux-xxs1500_2.4.21.bb
Users of these machines may want to use noatime flag instead.
Also expect breakage if your machine uses old kernel and default fstab.
