Re: [libvirt PATCH] network: Use single quotes in default network configuration

Whenever libvirt is upgraded on a Debian system, the user will be prompted along the lines of Configuration file '/etc/libvirt/qemu/networks/default.xml' ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. *** default.xml (Y/I/N/O/D/Z) [default=N] ? d --- /etc/libvirt/qemu/networks/default.xml 2020-08-04 12:57:25.450911143 +0200 +++ /etc/libvirt/qemu/networks/default.xml.dpkg-new 2020-08-03 22:47:15.000000000 +0200 @@ -1,19 +1,11 @@ -<!-- -WARNING: THIS IS AN AUTO-GENERATED FILE.

Since the canonical version of all libvirt XML documents (as returned by the various vir*GetXMLDesc() APIs) as well as the on-disk representations use single quotes, let's use the same for configuration files we install as well.
