I'd use PWD for everything to avoid confusions.
Coincidentally though, the systemd units would make use of
`WorkingDirectory=` to set it to SNAP_DATA for root run services and
SNAP_USER_DATA for user ones (when those come).
The binaries one is quite tricky because I'll try to access a file and
all of the sudden I'll get "No such File or directory" style errors.
$ cd ~
# in theory this would be just `vim` in the future.
$ vim.editor Documents/myfile
I still prefer SNAP_USER_DATA though.
