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 ：viewtopic.php?p=945488&hilit=openvpn+docker#p943450
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.
