If there is no most recently configured version
- <prgn>dpkg</prgn> will pass a null argument; older versions
- of dpkg may pass <tt><unknown></tt> (including the
- angle brackets) in this case. Even older ones do not pass a
- second argument at all, under any circumstances.
+ <prgn>dpkg</prgn> will pass a null argument.
+ <footnote>
+ <p>
+ Historical note: Truly ancient (pre-1997) versions of
+ <prgn>dpkg</prgn> passed <tt><unknown></tt>
+ (including the angle brackets) in this case. Even older
+ ones did not pass a second argument at all, under any
+ circumstance. Note that upgrades using such an old dpkg
+ version are unlikely to work for other reasons, even if
+ this old argument behavior is handled by your postinst script.
