No.

I believe you have done something wrong. Or is your /home on the sdcard?

It is impossible to create a symbolic link _on_ a FAT32 filesystem

But it sure is possible to create a symbolic link _to_ a FAT32 folder.

The link should be created in /home/root, which hopefully is jffs2 on 
the internal flash?


My own case:
/home/root is in the internal flash, jffs2 filesystem
tangogps wants to use /home/root/Maps

My actual map folder is /media/card/kart , and the filesystem for that 
doesn't matter at all. I used this command:

ln -s /media/card/kart /home/root/Maps

If you have tried to start tangogps, then it may have created 
/home/root/Maps already and populated it with a high-level world map. 
You must delete this folder before you can use the "ln" command.

Whatever folder you link _to_ (in my case, /media/card/kart ), it must 
contain a folder named OSM and under that, various numbered folders.
You cannot link directly to the folder named OSM, you must link to the 
level above it. If your map folders aren't in a folder named OSM, fix 
that first using "mv".




If your /home/root _is_ on FAT32 and there isn't room for the maps in 
the same filesystem, then you will have to reformat indeed!
