I’ve been rebuilding my Raspberry Pi collection from scratch, and moving from Ubuntu Server to Debian/Raspbian Bookworm. One of the tasks that I quickly tried to automate was reconnecting my CIFS mounts. I wanted to do it better, and came across this method, with the help of ChatGPT, to mount them at boot:
#!/bin/bash
# Check if the script is run as root
if [[ $EUID -ne 0 ]]; then
echo "This script must be run as root"
exit 1
fi
# Check for correct number of arguments
if [ "$#" -ne 4 ]; then
echo "Usage: $0 <RemoteDirectory> <MountDirectory> <Username> <Password>"
exit 1
fi
REMOTE_DIR="$1"
MOUNT_DIR="$2"
USERNAME="$3"
PASSWORD="$4"
CREDENTIALS_PATH="/etc/samba/credentials-$(basename "$MOUNT_DIR")"
# Escape the mount directory for systemd
UNIT_NAME=$(systemd-escape -p --suffix=mount "$MOUNT_DIR")
# Create mount directory
mkdir -p "$MOUNT_DIR"
# Create credentials file
touch "$CREDENTIALS_PATH"
echo "username=$USERNAME" > "$CREDENTIALS_PATH"
echo "password=$PASSWORD" >> "$CREDENTIALS_PATH"
chmod 600 "$CREDENTIALS_PATH"
# Create systemd unit file
UNIT_FILE_PATH="/etc/systemd/system/$UNIT_NAME"
echo "[Unit]
Description=Mount Share at $MOUNT_DIR
After=network-online.target
Wants=network-online.target
[Mount]
What=$REMOTE_DIR
Where=$MOUNT_DIR
Type=cifs
Options=_netdev,iocharset=utf8,file_mode=0777,dir_mode=0777,credentials=$CREDENTIALS_PATH
TimeoutSec=30
[Install]
WantedBy=multi-user.target" > "$UNIT_FILE_PATH"
# Reload systemd, enable and start the unit
systemctl daemon-reload
systemctl enable "$UNIT_NAME"
systemctl start "$UNIT_NAME"
echo "Mount setup complete. Mounted $REMOTE_DIR at $MOUNT_DIR"Code language: Bash (bash)I’m sure this is totally insecure and a terrible idea, but it works for me so back off, buddy!
Please don’t follow me as an example of what to do, but take this code for anything you need.
