If you load it as a unc at boot time this is loaded before the backup is loaded so if you put /ramdisk/etc/smb.conf in your filetool.lst files it will get loaded over whatever the unc loads up. This works OK with the default boot settings (i.e. unionfs) as etc is a union with /ramdisk/etc & so writable. I use this method, but do get some stragne things happening. If I look in /etc/samba I can't see smb.conf listed, but 'vi smb.conf' does edit the file. If I look in /ramdisk/etc/samba the file is visible using 'ls' or in emelfm. There is another version of the file in /opt/samba/etc/samba which is loaded with the unc, but isn't linked to the one in /etc/samba (i.e. if you edit the one accessible through /etc/samba or /ramdisk/etc/samba it has no effect on the one in /opt/samba/etc/samba - as you would expect since it is ro). For info I've appended the output of listu on my machine with Samba.unc loaded. I'm uncertain how unionfs decides which of the files it decides to use when /etc/samba/smb.conf if accessed, but it always seems to pick up the one I want (i.e. the edited one in /ramdisk/etc) & that is the one that is stored & reloaded by the backup system when selected in filetool.lst.
