feat: btrfs assistant & grub-btrfs (#789)
* Btrfs Assistant(+snapper), grub-btrfs Setup added Adds fedora-btrfs-assistant.sh, updates tab_data and documentation. * updated doc, ta_data and sh * enable grub-btrfsd service added * updated some wording in notices. * updated wording and add prompts for actions * added fix for a possible grub error also some more enhancements and wording improvements. * user action removed reinstall snapper action removed because removing and reinstalling snapper is a very unlikely action. and also snapper can't handle ./snapsots folder in the disk after reinstalling: "creating btrfs subvolume .snapshots failed since it already exists". * firs snapshot order changed home snapshot taken first because it's config can be saved to first root snapshot. * better explanations in user prompts * improved y/n loop * formatting improvements * formatting improvement Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * formatting improvement Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * Update task list Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * removed a inline comment Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * removed an unnececary inline comment Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * removed an unnececary inline comment Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * improved sed -i Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * improved sed -i Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * improved sed -i Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * newlines removed from tab_data.toml Co-authored-by: Nyx <nnyyxxxx@protonmail.com> * btrfs detection moved to toml Co-authored-by: Nyx <nnyyxxxx@protonmail.com> * data.preconditions added - escalation tool used * $PACKAGER replaced with dnf * re-added packager Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * re-added packager Co-authored-by: Adam Perkowski <adas1per@protonmail.com> * usergide updated with docgen * typo fix --------- Co-authored-by: Adam Perkowski <adas1per@protonmail.com> Co-authored-by: Nyx <nnyyxxxx@protonmail.com>
