^^ And run again after wiping.

I added the ls /data to show /data is mounted

Advanced/Wipe Dalvik Cache does a quick rm -rf /data/dalvik-cache

We do not have /cache/dalvik-cache for system caches and /data/dalvik-cache for user apps.

that's the only difference, that's why wiping cache partition does nothing for us.

keep in mind recovery is made by a cyanogen buddy for his buddy's rom, his buddy inludes the associated rom manager in his rom, everyone is happy, in CM land.

End of story, dalvik wiping works, just don't expect them to cater to us. We benefit from their work GREATLY, i acknowledge that, and i am glad they are around, they just don't cater to people.

Use it or not, your choice.
