====== Steam Deck ======
===== Mount ROMs share =====
Create mount directory

<code>
mkdir -p /home/deck/ROMs
</code>

Make sure your credentials file is correct
<code>
~/.smbcredentials
</code>

Contents:
<code>
username=YOURUSERNAME
password=YOURPASSWORD
</code>

Correct permissions:
<code>
chmod 600 ~/.smbcredentials
</code>

Create the systemd mount unit
<code>
sudo nano /etc/systemd/system/home-deck-ROMs.mount
</code>

<code>
[Unit]
Description=SMB Share for ROMs
After=network-online.target
Wants=network-online.target

[Mount]
What=//192.168.1.23/ROMs
Where=/home/deck/ROMs
Type=cifs
Options=credentials=/home/deck/.smbcredentials,vers=3.0,uid=1000,gid=1000,file_mode=0644,dir_mode=0755,actimeo=1,nounix,_netdev

[Install]
WantedBy=multi-user.target
</code>

**Important**:
The filename must match the mount path using systemd’s naming rules:

/home/deck/ROMs  →  home-deck-ROMs.mount


Create the automount unit (optional but recommended)
<code>
sudo nano /etc/systemd/system/home-deck-ROMs.automount
</code>

Paste:
<code>
[Unit]
Description=Automount SMB Share for ROMs

[Automount]
Where=/home/deck/ROMs

[Install]
WantedBy=multi-user.target
</code>

Enable + start both units
<code>
sudo systemctl daemon-reload
sudo systemctl enable --now home-deck-ROMs.automount
</code>

Systemd will not mount it immediately — because automount waits until something touches the folder.
To trigger it:
<code>
ls /home/deck/ROMs
</code>

If successful, your SMB share mounts instantly.
