Makes sense in principle. Do you know if any packages yet ship with sysctl files (systemd does, but that doesn't count ;-) )? If so they could call this in post_install, so that makes sense to me. -t

I don't know if package ship sysctl files, but there is few case where this should be done. It's more an admin facility to tweak a system and be compatible with other distro. Idea behind this commit, is to have the same behaviour in initscripts plugin. If package want trigger it, he can do it with the initscripts binary, calling /usr/lib/initscripts/arch-sysctl. But it's initscripts oriented and not really compatible with systemd and should directly call "sysctl -p hisfile.conf" instead. -- Sébastien Luttringer www.seblu.net

I'm not necessarily opposed to this, but could you point to some usecases? I assume this will allow us to remove some code from some packages and have them ship a config file instead? Some examples like this would be nice. -t

You can test this feature by droping a file wine.conf in /etc/binfmt.d with the following content: # Start WINE on Windows executables :DOSWin:M::MZ::/usr/bin/wine: After a reboot, or a succeful run of /usr/lib/initscripts/arch-binfmt, you can run ./toto.exe and it will be lauched automagically with wine as interpreter. You can read more detail on this linux feature in the kernel documentation[2]. I don't believe package currently use this feature. There is a wiki page with example for java[3] where the job is done in rc.local. This patch will allow to do it by initscripts config.

IMHO the manpage should stay the same, and we should rather change rc.sysinit to always ensure the symlink (the only point of doing the copy is in case /usr is not mounted, but we don't support that any more). -t
