Indeed, this makes installing a script directly into /etc/rc.d/ a strict no-no under Gentoo, as all insertions into a run level have to be performed by the sysadmin by hand; other Linuxes are more permissive, though. Consequently, I would never want any program to install anything into that directory, except by the rc-update program run by hand. -- Regards, Dave [RLU #314465] *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* david.w.n...@ntlworld.com (David W Noon) *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* signature.asc Description: PGP signature ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] Detecting what is the linux distro
It's not just that. Lets say you have a UI for IPTables. In Redhat based, it will be located under /etc/sysconfig/iptables . On debian based, it should be under /etc/networking/post-config or something like that (don't have a debian based machine here), and so on... Please note that I do not talk about exited scripts such as Arno's scripts or shorewall, just plain IPTables client, and it's different on each distro. If you require to read settings of the system (that located at /etc/), no one guarantee you that all distro's will store then at the same place. That's the reason why so many software/driver vendors are so reluctant to release Linux support. For example Foomatic drivers for CUPS, the drivers of the printers in Mac OS-X are the same as with Linux, but many vendors ignore Linux just because this mess. So it's not just lets create a package and get over with it, It's not that simple.

That's the reason why so many software/driver vendors are so reluctant to release Linux support. Nonsense. Most vendors are lazy, some are scared of licensing, etc. Most importantly they think they can get away with not supporting linux because of the small market share. For now.
