Let us suppose, as a not entirely hypothetical example, that youare transplanting the system disks from a Solaris 10 install from aSunFire X2100 to a SunFire X2200. While both machines have four onboardnetwork ports, two Broadcom and two nVidia, they are not quite thesame hardware, enough so that if left to its own devices Solaris willconsider the new machine's NICs to be bge2 , bge3 , nge2 , and nge3 (instead of bge

Here's something that I want: I want a version control system (ideally adistributed one) that can preserve file timestamps. I'm looking for sucha weird feature because I happen to have created something that I want to put under version control where (some of the) filetimestamps are significant and need to be preserved.

(This is yet another hazard of using files as entries , albeit in a slightly different form.)

This is an uncommon feature in version control systems at the best oftimes

Wietse Venema's tcpwrappers is mostly used forcontrolling access to services run from inetd or your local equivalent,where you are not expecting high performance or high load. However, itcan be built as a library that you link your daemon against, and somedaemons are.

(At least on Linux, both OpenSSH and the portmapper are built thisway.)

It turns out that there is a small drawback to using tcpwrappers thisway in some sorts of high-performance applications, specifically inapplication where you expect a
