Am I going to run into any problems down the line? Thanks in advance.

itbedave,
The only thing I can think of as to why this works comes from zach.xtr dev thread over on XDA where he says:
Cache Location (Cache2cache):
By default, the dalvik-cache has been relocated from the internal /data/dalvik-cache/ directory to the internal /cache/dalvik-cache directory. The Eris comes with an internal /cache/ file block of 130mb that is not used! After reviewing a number of xda member file system usage reports (thanks xtrROM and xtrSENSE users!) the MOST reported use of this space was 5%... So by moving the dalvik-cache to this free area you now have over 150mb on internal /data/ for apps and over 75mb in internal /cache/ for dalvik-cache. This means that you can probably install close to 100 apps WITHOUT having to partition and move anything to the SD Card ext!
Pretty cool, really. So, I'm wondering (guessing, really) if your Dalvik-cache was rebuilt anyway for you when you first booted (like it would have to be if you wiped your Dalvik-cache).
Anyone know for sure?
Cheers!
