-Subject: [PATCH] btrbk: Prefix PATH instead of resetting it.
-
-Some distros don't even install use /usr/bin, /sbin, etc. (notably
-NixOS). Instead, they use PATH to specify which programs are available
-to a given executable.
-
-This patch changes the behavior or `btrbk` so it extends PATH with its
-own search paths instead of resetting it. This allows users and distros
-to specify their own custom location for `btrfs` via `PATH`.
