Hi, Looking for some clues as to how to add a user to AIF install. Have been looking at examples and trying out useradd under them but am getting seg-faults. Any advice on how to get it working? MrG

[arch-releng] [PATCH] Fix detection of virtio block devices
by Kevin Shanahan 26 Feb '12

26 Feb '12

When installing on a KVM guest with virtio block devices, the disk detection fails because of missing 'type' file in sysfs for these devices. Try identifying via the 'vendor' file if 'type' is missing.

[arch-releng] [RFC][archiso] A rain of patches
by Gerardo Exequiel Pozzi 24 Feb '12

24 Feb '12

Note if you want to test this without using util-linux 2.21 (not released yet), must use these boot params: earlymodules=loop loop.max_loop=16 Currently archiso_shutdown is broken due recent /lib -> /usr/lib of udev. One patch in this series fixes it, this is mostly important when using cow_device otherwise there is no harm. If there any plans to make new officials images soon (before util-linux 2.21), I like to push all these patches, plus adding temporary workaround (mentioned boot params) to syslinux.cfg.
