media share set to webroot after 4.2.19 upgrade

simple :

Samba is configured to read Shares.conf but also /etc/frontview/samba/addons/addons.conf

extract of /etc/samba/smb.conf

include = /etc/frontview/samba/smb.conf.%a
include = /etc/frontview/samba/Shares.conf
include = /etc/frontview/samba/Shares.conf.%U
include = /etc/frontview/samba/addons/addons.conf

All the addons are using /etc/frontview/samba/addons/addons.conf so the Shares.conf only contains default shares and shares created by frontview

example :

/etc/samba/addons/addons.conf

include = /etc/frontview/samba/addons/addons-config.conf

and /etc/samba/addons/addons-config.conf

[addons-config]
  path = /c/addons-config
  oplocks = 1
  force create mode = 0666
  create mask = 0666
  force security mode = 0666
  force directory mode = 0777
  directory mask = 0777
  force directory security mode = 0777
  admin users = "admin","Administrator"
  writeable = 1
  guest ok = 1
  vfs objects = recycle
  recycle:versions = 1
  recycle:repository = Recycle Bin
  recycle:subdir_mode = 777
  recycle:keeptree = 1
  recycle:directory_mode = 777

sonds like samba in 4.2.19 is not reading the addons.conf and do bad things at boot
by default the nas at boot take a look in /c/ and if a directory is not declared as share it add it in Shares.conf but with 4.2.19 it does silly things
