Hi
As you probably aware arch is phazing out rc.conf and initscripts to be replaced by systemd in the coming weeks / months , i recently took the plunge and went native systemd on 2 arch 64 bit installs i have at home , i wrote a guide to help others make the transition , ( which worked flawless on both my installs and at least 6 other folks i know of who followed my guide using x86_64 machines) i was asked by a fellow archlinuxarm forum user to test my method on the RPI ArchArm , i duly obliged and im sorry to say it didnt work , i had sysctl I/O errors and could only boot to a shell with no jobs so couldnt even login or use pacman , so this is just a heads up to ArchArm users , if anyone has successfuly went native systemd on ArchArm id be interested to know how they accomplished it.
regards
