Caldera has signed an agreement with Linux services provider Acrylis, in an attempt to position itself as a serious contender to market leaders like Red Hat.The Acrylis software, WhatIfLinux, will be tied in with Caldera's recently released Volution management and computer software. The new solution, available in the second quarter of this year, is being launched as a rival to the Red Hat Network, and will offer a subscription-based service to allow company administrators to update their Linux software over the network. Unlike the Redhat Network, the Caldera solution will be offered as a rebranded product for sale through Caldera's network of resellers. SuSE Linux also announced a worldwide agreement today with IBM. The Linux company will provide technical support to IBM customers using the open source operating system.
