I installed DietPi on a VM with Debian Bookworm installed on it, which had shared directories from a Windows PC mounted on the VM. After installation, the contents of these directories were deleted. I assume this is because the directories were not unmounted during the installation.
Where were the folders mounted to?
Why not using our VM images?
hi,
the folders was mounted on the host machine, and after install, i seen than the files was deleted
Because, i wanted to try the install script ! 
I don’t find where this problem occured…But it’s easy to reproduce this !
Have a nice day
which folder? where? exact mount point?
it’s with this script i wrote :
#!/bin/bash
# This script allows mounting and unmounting shared directories on Raspbian in a VMware VM
# Display the user's home directory path
REPERTOIRE_UTILISATEUR="$HOME"

}

selectionner_repertoire_a_demonter() {
# Get the list of mounted directories using vmhgfs
REPERTOIRES_MONTES=$(mount | grep vmhgfs | awk '{print $3}')
# Check if no directories are mounted
if [ -z "$REPERTOIRES_MONTES" ]; then

so they are mounted to /home? I mean, you could just say what the mount point is without me having to read through some scripts first.
Yes they are mounted to /home
Sorry, i believe that can help you to have the script i used
ok I guess this one might be responsible for your situation
It’s going to clean user home directory as part of the general clean up
Hi
I don’t know if it’s necessary to clean the home directory (and mounted path too 
) but as they are not warning before it will be a problem in some case !
A minimum thing would be to unmount all shared path before run steps script.
Happy to find this “bug” (and sorry if i do mistake on translation but with the script you seen than i’m french 
)
Have a nice day and thanks for dietpi !
well the system will be cleaned up completely. We remove all software title as well as all users. This is how it is intended.
something that could certainly be included
Ok, perhaps a warning message to indicate that it’s necessary to backup datas before launch dietpi installation…
i just lost few data because i done backup one hour before and now i know but for others it will be most secure 
well, it is rather a rare case that a user configures his system, mounts things and only then executes the install script. And even with a warning, there are certainly still users who ignore it. But yes, we will take it into consideration
Thanks 
Have a nice day
