## Export TMPDIR environment variable for borg via python
## Python requires a writable temporary directory when unpacking borg and
## executing commands. This defaults to /tmp but many systems mount /tmp with
## the 'noexec' option for security. Thus, we will use/create a 'tmp' folder
## within the BORG_BASE_DIR and instruct python to use that instead of /tmp
# check if BORG_BASE_DIR/tmp exists, if not, create it
