Why no Disk Mounting on GUI for CT?

[kotakomputer]

We can mount a disk to CT using CLI like this:

pct set 100 -mp0 /mnt/mydisk,mp=/mydisk

But why this feature not available on GUI?

You are referring to Bind Mount Points - which can only be managed by the CLI.

I'm guessing the decision not to have them manipulated by the GUI is due to the fact that:

1. Bind Mount Points are not considered to be managed by the storage subsystem.

2. With regular (& advised) unprivileged containers, you may often run into permission/user/group/ACL problems with these mount points, so you will anyway need todo other CLI shenanigans to get these to work.

3. Bind Mount Points can cause a serious security leak if the wrong source directory/s are used.

There are no reason to disable it in the GUI while a CLI able to do it.

The security reason has no impact while using a mounting disk as NFS share to create a CT/VM, because Permisions/ACL inside the CT/VM storage.
