'install -d' has an issue compared to 'mkdir -p': it doesn't
respect existing directories. It will set the ownership, file
mode, and SELinux contexts (and any other property that would be
set by install(1) to a newly-created directory), overwriting any
existing properties of the existing directory.
'mkdir -p' doesn't have this issue: it is a no-op if the
directory exists. However, it's not an ideal solution either,
since it can't be used to set the properties (owner, mode, ...) of
a newly-created directory.
Therefore, the best solution is to use install(1), but only after
making sure that the directory doesn't exist with test(1).
