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?
Well, honestly, the solution I like more than the others is having the python tar bug fixed and be free to use the python tar lib.
I would like to exclude cpio: it's on rpm based distro but not commonly available on others.
I would like to exclude the RTFM solution, having it working out of the box.
So my second choice is using a self extracting script. If you think pyar is a non standard tool, do you have considered the use of shar? Or do you think it's also a non standard tool?
shar needs dependencies on remote: - md5sum - uudecode
