# Set TMPDIR to / to avoid issues with the default /tmp directory on Ubuntu/Debian.
# The TinyTeX installer downloads a tarball with files owned by 1001:1001. When extracted
# as the root user, these files keep the original ownership with default tar options
# (--no-same-owner to disable that behavior). Ubuntu/Debian have fs.protected_regular
# enabled by default, disallowing root from writing files owned by other users in /tmp,
# which the TinyTeX installer needs to do. Setting TMPDIR to / works around this issue.
