[Samba] Custom dns_update_list file

[Victor Rodriguez]

Hello,

I have the need to set specific IPs in DNS to allow clients to correctly 
communicate with Samba. I archieve this editing 
samba/private/dns_update_list and replacing the A record for the domain. 
This works until some package update replaces it with the default one.

Is there any way to properly set a custom dns_update_list that does not 
get overwritten?

I can't use the interfaces directive in smb.conf as the same interface 
has more than one IP.

Thanks in advance
