Frustrated by the use of the sh|ttifying FAT32 FS on MyDocs and the stupid way it allocates space I decided I wanted to move 'maps' folder to /opt so it could nestle down in a 'real' FS.

The only problem is you cannot symlink (derp) on a fat32. Creating a FS image seemed like to much of of a kludge (besides fat32 doesn't allow sparse files (herp)). Further to this when you plug in USB and mass storage mode everything gets unmounted (herp derp).

Fortunately with nix you can mount pretty much anything, anywhere!


MyDocs partition is mounted and unmounted by two scripts when you enable/disable mass storage mode. They are:

Code:
/usr/sbin/osso-mmc-mount.sh
Code:
/usr/sbin/osso-mmc-umount.sh
So I created a directory /opt/maps_oso and copied the contents of ../MyDocs/.maps to it. Then in osso-mmc-mount.sh I added the line:
Code:
mount --bind /home/opt/maps_osm /home/user/MyDocs/.maps
After line 72.

I also had to include:
Code:
##unmount extra stuff
  umount /home/opt/maps_osm
  sleep 2
##
after line 32 in osso-mmc-umount.sh.


While this is very specific to my case it may be useful for other people who want to have things automatically mounted/unmounted/linked to the exported MyDocs partition.
