# has the unfortunate side effect of breaking running mysql_install_db with
# the --user=mysql argument as mysqld uses TMPDIR if set, and is unable to
# write temporary tables to that directory.  To work around this issue, we
# create a subdirectory inside TMPDIR (if set) for mysqld to write to.

# Idea from Ben Hekster <heksterb@gmail.com> in bug#31164
