2) Some users who do not wish to create an ext3 on their SDCards would like to use Froyo Apps2SD to free room on their /data partition. However, there seems to be some confusion on creating conflicts in the Dalvik.
a) So, if you have DT a2sd installed and you do NOT have an ext3 set up, is it then ok to move apps to the .android_secure folder using Froyo Apps2SD?
b) If you do have an ext3 set up and you want to use Froyo Apps2SD instead and you run a2sd remove, will that permanently stop a2sd from looking at ext3 for apps?
c) Would ext3 be made available again by typing a2sd reinstall?
a. Yes. Froyo Apps2SD and Darktremor Apps2SD use different concepts to achieve the same goal. You can use Froyo Apps2SD without setting up an EXT partition.
b. So long as the flag file /data/.noa2sd is present, the EXT partition will be mounted, but not used for applications. The reason for this is that you may want to use it for dalvik-cache or program data (as those aren't even addressed in Froyo Apps2SD).
c. Running a2sd reinstall will put your applications back on the EXT partition and activate it for application use...."
