pkexec removes most environment variables, which can prevent Timeshift from starting on some distributions. For example: https://www.reddit.com/r/voidlinux/comments/t1f2it/timeshift_gui_error_gtkwarning_cannot_open_display/?rdt=35784 |

instead of using env in the timeshift-launcher like proposed in linuxmint#384, the timeshift process itself now searches its parents until it finds a process that is not owned by the same user as timeshift (root) and then copies interesting environment variables from there. This allows pkexec to handle the command correctly.
