Re: [Engine-devel] [Users] [Feedback required][host-deploy] Fedora-19 misses tar at minimal setup
Hello Again,
I tend to keep state as-is, require tar at host machine.
Whoever installs Fedora minimal should install tar manually.
I hope Fedora people will add tar per some of the requests, as tar is important utility in
*NIX environment.
I do not think that the extra complexity is required.
If you strongly think otherwise, then I prefer to merge the self extracting python
script.
Speak now, and emphasis.
Regards,
Alon Bar-Lev.

Subject: 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?

Alon Bar-Lev
