With all respect, it is a quite questionable statement. I would rather say "it is not the _host_ administrator business to guess what my _application_ needs". When my program looks for DNS, it means DNS, not any local hacks pretending to know what the host name space "should" look like. Thanks Heaven DNS is quite near being a global name space, don't cripple it. Seriously, I know how useful "local hacks" can be, but they remain hacks anyway. That is, I can not buy that the "damn good" reasons are good. It's a shame that the tradition confused the global name service with the local ones. For the record, I am using a patched version of uClibc which is run-time configurable (per process, not per host) concerning most of the usually hardcoded paths like "/etc/hosts" or "/etc/passwd". This is extremely useful and sometimes the only way to let a program function sanely (despite the choices and guesses of the local administrator or OS provider). (setuid can be safely done with such a library too, by small setuid wrappers which contain hardcoded values for the runtime configuration variables and run the target binaries) RL _______________________________________________ uClibc mailing list [email protected] http://lists.busybox.net/mailman/listinfo/uclibc
