Hello Guys, While i work out the snapper on fedora 25 I've learnd more about python and snapper. Here the changes: Snapper: Created a combat util-linux 2.24.2 from fedora 20, static only. This make snapper rollback available (needfull thing). Tryed to patch snapper, there are to many changes. This will not breake centos 7 system. Only works for x86 / amd64 only this days & Centos 7, removed many condition. Grub2-Btrfs: Removed "Requires: grub2", because that will install grub2 on efi systems. yum-plugin-snapper: - Add gpl v3 for now - Complete rewrote the plugin against the snapper dbus interface. - filesystem root level check - add single shot option, as it was on fedora before I patched it. - more flexible as other ones I saw around. - conflicts yum-plugin-fs-snapshot Everything can be found at: https://copr.fedorainfracloud.org/coprs/andybe/Centos7Btrfs/ Snapper-Gui: Needs epel-release because of python34 python34-pygobject3 is one of the badest hack inside spec file. I wanne see it run with snapper-gui and compile on copr. can be found at https://copr.fedorainfracloud.org/coprs/andybe/CentOS7Python34/packages / Everything was tested on a Virtual Machine: - Snapper-GUI - snapper rollback - yum-plugin - every option. - grub2-btrfs The only thing I still want to care is the grub2-btrfs plugin, so it fits to CentOS 7. Then the personal project is done. At this time I will reinstall CentOS on my laptop on btrfs and use backup by send & receive on a blockdevice ZFS at my home server or other storage with btrfs. I will see. Hopefully turn work into fun :-). Sincerely Andy PS: It's up to you to get a taste on.
