It shouldn't be a problem. Unless you have Perl scripts that directly poke at the Linux kernel, I'd expect nearly all scripts (Perl and otherwise) to be mostly immune to changes in the kernel. This is roughly equivalent to the way that you almost never have to reinstall all your software every time you run Windows Update on your PC or Software Update on your Mac or up2date or whatever on Red Hat Linux. Modern systems have long been designed in layers so that internal changes to one layer (e.g. kernel updates) shouldn't matter to software at other layers (e.g. Perl or Perl scripts) that depend on services from those underlying layers. (This is also like how OSI and TCP/IP work -- changes at one layer such as the transport [think kernel] aren't visible and don't matter to services at a higher layer such as the application [think Perl].) So, in general, don't worry about it too much. Test to be sure, but you are very likely to find that things just continue to work. -- Chris Devers pÝU·¡qÃRá²
