We are trying to setup a virt-sandbox-service where we are mounting over /etc/aliases and /etc/aliases.db

When we setup the container, /etc/aliases gets mounted but /etc/aliases.db does not.

I experimented with /etc/dan and /etc/dan_long and saw the same behaviour, once I changed to use /etc/dan1 and /etc/dan_long both containers worked.  

virsh edit

shows the correct xml.

Here is the command we were using to set this up.

virt-sandbox-service create --copy -N dhcp,mac='52:54:00:ec:b6:c4',source=virb\
r1 -m host-bind:/etc/aliases.db=/containers/$name/etc/aliases.db -m host-bind:/\
etc/aliases=/containers/$name/etc/aliases -m host-bind:/etc/resolv.conf=/contai\
ners/$name/etc/resolv.conf --unitfile postfix.service -p /var/lib/libvirt/files\
ystems $name
