not sure if I've seen it mentioned here before, but recently I've been reading about using cronmod (http://forum.xda-developers.com/show....php?t=1716124
obviously our 2.2 edge machines don't have init.d, but something like script manager or autostart root should do the same function.
when I have some free time I'll mess around with the 40int2ext script (INT2EXT+ - it's the recommended one apparently - http://d-h.st/xwB
- link goes to CWM-type recovery installer .zip, actual necessary single script file is in system/etc/init.d/ of the zip)
at first glance it looks like the script isn't doing anything really beyond the abilities of the edge (well aside from ext4 support I imagine) so it will almost work as-is - other than the missing zipalign binary, which is easy enough to get (e.g. http://forum.xda-developers.com/showthread.php?t=594615
) but still needs manual cli install.
if something interesting happens I'll mention about it...
(there's also still the problem of the "missing/damaged" sd card error - fix is easy and could simply be added to the script, although the error would still show up, not to mention sleep/resume or add/remove card could be problematic...)
