=head2 $si->prepare_os()

Use os-specific tools to find out more about the operating system.

Abbreviations used in AIX OS version include

 ML   Maintenance Level
 TL   Technology Level
 SP   Service Pack
 CSP  Conclusive/Last SP
 RD   Release Date (YYWW)

When the OS version reports as C<AIX 5.3.0.0/TL12-05>, the C<05> is
the C<SP> number. Newer versions of AIX report using C<TL>, where older
AIX releases report using C<ML>. See C<oslevel -?>.
