media share set to webroot after 4.2.19 upgrade

perhaps a temporary fix :

at startup readynas overwrite the Shares.conf with Shares.conf-sav

but the sav file is not correct so what I have done on a unit :

Recreate a correct Shares.conf with all the shares then copy it as Shares.conf-sav then reboot the unit and it's ok :)
