https://en.wikipedia.org/wiki/Shim_%28computing%29 In short: A shim is an adaptation or compatibility layer that enables software to use functionalities of other components not actually present on the system (or present, but in an older version, or the like). It does so by providing the desired functionality itself, or mapping it to other third party libraries, or simply by faking it. A typical example would be a "thin" wrapper library that maps one API (-version) onto another API (-version). (In technical engineering context, a shim is generally some kind of lining plate or metal spacer (e.g. a simple washer) used to mechanically adapt pieces of machinery or equipment.) > (in the context of systemd and EFI), The systemd-shim package in debian allows software to use systemd functionality without the need of actually having systemd installed and running as PID1 on the system. Not sure about the (U)EFI context. I assume it would be a signed bootloader that allows some kind of chain-loading other arbitrary (unsigned) OS kernels. > but also *easy enough* > to explain it to some colleagues at work? That would depend on where you work, and how well educated your coworkers are. ;-D HTH, Regards Urban _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
