I have followed your guide to install aMule on OMV and I must cogratulate you, It works perfectly. There are however a few things missing that I believe would be of help to other users of aMule in OMV.
Within the folder /home/aMule/.aMule you will find a file called shareddir.dat, this can be used to add shared folders to aMule.
Example of shareddir.dat file as follows:-
/home/guest/
/temp/
/mnt/share/
/mnt/ed2k/
/var/download/
My own shareddir.dat is as follows:-
/media/2710098d-6417-4e56-a61a-2a5c399955da/External1/Movies/
I would also like to see a plugin made of this aMule installation as if you need to stop aMule for some reason it is rather convoluted. A much better way of stopping or starting aMule would be to have a start and a stop button within the Web Management page of OMV
Apart from the above I'd like to say well done.
