fix: resolve bugs in samba.sh and Dockerfile

- Fix chown syntax: changed 'smbuser.' to 'smbuser:smb' for correct group assignment
- Fix paths with spaces in perms(): use 'while read' instead of 'for' loop
- Add quotes to $file variable in import() to prevent word splitting
- Remove /etc from VOLUME declaration (too broad, causes unexpected behavior)

 ### Fixed
 
+- **Fixed chown syntax error in perms function** (samba.sh:122)
+  - Changed `smbuser.` to `smbuser:smb` for correct group assignment
+
+- **Fixed paths with spaces handling in perms function** (samba.sh:121)
+  - Replaced `for` loop with `while IFS= read -r` to correctly handle paths containing spaces
+
+- **Fixed unquoted variables in import function** (samba.sh:112-113)
+  - Added quotes around `$file` variable to prevent word splitting issues
+
+- **Removed /etc from VOLUME declaration** (Dockerfile:83)
+  - `/etc` is too broad and can cause unexpected behavior with system configurations
+
 - **Share-specific parameters not overriding global settings** ([#issue](https://github.com/upagge/samba/issues))
 
   **Problem**: When creating public shares with guest write access, the `-G` parameters for individual shares did not override the global `force user` and `force group` settings from the base `smb.conf`.
