Re: [Engine-devel] [Users] [Feedback required][host-deploy] Fedora-19 misses tar at minimal setup

Hello All, Starting the discussion again... I would like to receive feedback regarding how we should cope with a state presented to use by Fedora. Fedora-19 minimal setup does not install tar utility which is required to deploy files during the host-deploy process (Hosts->Add Host). I guess because of 2.8M in size (including translations) -- a standard commonly used utility was removed. There are three alternatives : 1. Instruct users who are using minimal installations to manually install tar utility just like they configure repository, dns, etc.. Benefit: simplicity. Benefit: use standard tools. Benefit: lower payload to transmit. Drawback: require tar at destination machine. 2. Do not use tar but self extracting python script, a patch is ready[1]. Benefit: ability to deploy environment in which tar is missing. Drawback: non standard tool at destination machine. Drawback: complexity within our code. 3. Do not use tar but cpio, a patch is ready[2]. Benefit: simplicity. Benefit: use standard tools. Benefit: lower payload to transmit. Benefit: ability to use Fedora-19 minimal. Drawback: cpio is even less common than tar, even if it exists in Fedora-19 it can be removed without anyone notice. Drawback: most other distributions will not have cpio in their minimal installation. [[[ There was 4rd alternative, using python tar module to deploy tar. However, there is a bug in that module when processing last block if empty. This is edge condition but happened to at least one of the users and I could reproduce it. ]]] What option do you prefer?
