I using the archlinux-hf-2012-09-18.img.
I start up the RPi and do pacman -Syu. It updates and tells me there are 4 pacnew files: group, gshadow, passwd and shadow.
I install vim and yaourt so I can use yaourt -C to find the pacnew files and vimdiff to see the difference.
Every one of those 4 files wants to remove dbus and ntp group and user.
1) Why? Where is that coming from?
2) Just to try it, I replace all 4 files and reboot and of course there is a river of error messages re: DBUS. I just pull the plug on the RPi and re-image the SD Card.
I use ArchLinux on my laptop so I know the dbus user/group is present so I'm wondering why are the pacnews telling me to remove them?
PS: The note to edit /boot/cmdline.txt and add the cycle_delay parameter also causes a kernel panic (but this is noted elsewhere as well)
