It will have to happen post yocto 1.3 (as far as I know), since the 3.0 kernel will be dropped at that point. For the short term, it's likely easier to backport/update unionfs than it would be to update the BSP .. but I can't speak for the time to be spent doing it :) Cheers, Bruce > >> Cheers, >> >> Bruce >> >>> >>>> >>>> -----Original Message----- >>>> From: yocto-boun...@yoctoproject.org >>>> [mailto:yocto-boun...@yoctoproject.org] On Behalf Of Chris Tapp >>>> Sent: Saturday, October 06, 2012 5:43 PM >>>> To: yocto@yoctoproject.org Project >>>> Subject: [yocto] Meta Intel / Cedartrail / Denzil - how to get unionfs in >>>> the kernel >>>> >>>> I' trying to enable unionfs in the 3.0.32 kernel for the cedartrail BSP >>>> under Denzil 7.0.1. >>>> >>>> However, the CONFIG_UNION_FS config flag isn't in the .config ... >>>> >>>> Is there something else I need to enable, or do I need to find another way? >>>> >>>> Chris Tapp >>>> >>>> opensou...@keylevel.com >>>> www.keylevel.com >>>> >>>> >>>> >>>> _______________________________________________ >>>> yocto mailing list >>>> yocto@yoctoproject.org >>>> https://lists.yoctoproject.org/listinfo/yocto >>> >>> Chris Tapp >>> >>> opensou...@keylevel.com >>> www.keylevel.com >>> >>> >>> >>> _______________________________________________ >>> yocto mailing list >>> yocto@yoctoproject.org >>> https://lists.yoctoproject.org/listinfo/yocto >> >> >> >> -- >> "Thou shalt not follow the NULL pointer, for chaos and madness await >> thee at its end" > > Chris Tapp > > opensou...@keylevel.com > www.keylevel.com > > > -- "Thou shalt not follow the NULL pointer, for chaos and madness await thee at its end" _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
