[feature] Ability to use either relative or absolute symlinks in `link` option

[RayZ0rr]

A clear and concise description of what you want to happen.

Add new values for the link option in the config value and dotfiles sections. The possible values can be:

• absolute :- Absolute symlink
• relative :- relative symlink
• link :- same as 'absolute' above for backward compatibilty
• nolink :- Copy
• link_children :- recursive (uses absolute)

  config:
  link_dotfile_default: (link|nolink|link_children|absolute|relative)
  dotfiles:
  f_file1:
  src: file1
  dst: ~/tmp/test1
  link: (link|nolink|link_children|absolute|relative)

Why

Absolute symlinks are portable within the system. Relative symlinks are portable across different machines with different usernames.

Sure that's doable, I'll work on it and let you know when I have something.

This is now available on the new version (v1.9.0).

You can have a look at the doc but globally this is what you requested: absolute (absolute symlink) and relative (relative symlink).

Old link: link will be automatically updated in the config to link: absolute.
