File Sharing lose settings after reboot

view full story

http://askubuntu.com – So I have ubuntu 11.10 desktop 64bit installed. Once I boot in i browse to a folder (on a mdadm array) i want to share on the network (to other windows and linux machines) i right click the folder and go to file sharing and select Share this folder, and alow others etc and allow guest and it works perfect, until I reboot and it loses all the settings. Does anyone know why this is happening? Maybe because i am not sharing them out as root? i can configure it manually via samba but this has got me curious. (HowTos)
