todo v1

[mkg20001]

• linking of files and db for removal

  • keep track of which links are from nix
  • if user-created file exist at target then bail

• linking via function hooks

  • so that modules can do their post-linking magic right away

• merge files

  • feature for files hook to add merge flag, merge strategy and comment type
  • will allow to merge files like /etc/systemd/system.conf instead of replacing them

• merge users

  • users that exist in nixos but not in host should be created
  • groups and group memberships aswell
  • track which users, groups, memberships are from nixos and remove them once they get removed in nixos / update them (shell, etc) when they get changed
  • add/replace the literal entries line by line

• run as systemd generator

  • will pollute the host less (easier to uninstall)
  • we no longer need to enable and start everything as that will be done for us

• proper file backup

  • when replacing a file from the host rename to $FILE.nix-unify
  • and store path for later restoration on uninstall-

• share nftables

  • optional
  • force flushRuleset to false
  • nftables service works in a way that is non-desturbing

• share networkd

  • all or nothing (there is no default config by default)

• share serviecs

  • service by service
  • also take service-dependencies into account
  • skip services which already exist on the host unless forced

• share sudoers

  • optional
  • include nixos sudoers config (maybe without defaults)

• share etc

  • optional
  • file by file (or folder by folder) inclusion

• use systemd-run, locking, etc like upstream

• handle service-restart, triggers, etc

• split into activation and switch parts

  • currently the script is an organically grown mess
