[Oberon] .aoshome and Work Directory on an SD card in UnixAos.

For years I've kept the "Work Directory" in UnixAos on an SD card 
reformatted to ext2.

Usage notes for flash storage commonly recommend against reformatting.
Eg.  https://wiki.laptop.org/go/Secure_Digital_card#Formatting

So I've reviewed the possibility of the Work Directory containing a 
FAT file system. Access speed might be a concern for some 
requirements; not for me.  An obvious small snag is the .aoshome link 
which the aos start script attempts to create. The FAT file system 
doesn't support links.  The link appears in Configuration.XML allowing 
File Manager to access "Module Sources" and "Fonts".  If aos fails to 
create .aoshome, File Manager doesn't show Module Sources and Fonts. A 
simple alternative to .aoshome is to hard code the location in two 
places in Configuration.XML. (The default location is /usr/aos.)

I haven't noticed any other difficulty with a factory formatted SD 
card. Anything to add to notes to help a novice?

Thx!                  ... P.L.
