Hi guys, Currently underscore naming is commonly used in LAN/WAN environment. As far as I known, there is only a few (none ?) internet wide host names with underscore. Allowing underscore is useful, but NOT mandatory, but for sysadmins it would be like ssh SUID or ppp SUID : an option when you "build world". I think that "non-vital" options should be supported but they MUST be switched by sysops at build world stage. > > There was a better patch that made it an option in resolv.conf, > rather than turning it on all the time. maybe a variable in make.conf would be better. Ex: make.conf: NOT_REALLY_RFC_COMPLIANT=YES In realworld: #ifndef NOT_REALLY_RFC_COMPLIANT #define hyphenchar(c) ((c) == 0x2d) #else #define hyphenchar(c) ((c) == 0x2d || (c) == 0x5f) #endif To conclude, if BIND authors say "support underscore is a reality we can't eclipse", let's follow them... regards, clem PS : sorry for my poor english ;-)
