Container mounts will create a directory as container store

OS Version : 7.14~7.15 Beta6
e.g.
/container/mounts/add name=etc_pihole src=disk1/etc dst=/etc/pihole
if src directory “etc” not exists,when the container start,it will auto create a folder,but its type is container store.So user can not use “Files” to add files to this folder.
Seems there’s already a similar problem here :http://forum.mikrotik.com/t/v7-1rc3-adds-container-support/151712/387
And another problem,Winbox “Files” can not create a folder,If you use other software, such as WINSCP, the permissions of this folder will be incorrect and cannot be changed. But “CREATE FOLDER” is normal useful on the mobile APP.
