Apps2SD is not possible

[anonymous]

Every Time, if I try to install an app to the SDcard or move it there, it stops:
(Move application)
Failed to move application.
(OK)

LOGCAT:

This could help by sloving the problem:

Well, you need a fixed kernel configuration, with enabled device mapper (MD + BLK_DEV_DM), and i guess proper crypto support for APPS2SD mecanism (twofish).

there is no compelling reason to install to SD. our images have 512MB in size. Loooots of free space.

If somebody contributes a full featured tested fix we will gladly integrate it of course.
