[Users] [Feedback required][host-deploy] Fedora-19 misses tar at minimal setup
Hello All, 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 two 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. [[[ There was 3rd 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. ]]] Regards, Alon Bar-Lev [1] http://gerrit.ovirt.org/#/c/17295/

Consider using cpio instead of tar. It is required to build initrd, so available in any installation. It is also supported by the library currently used in the engine to build the tar archive. -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.

Thanks Juan, it is good idea. I did not thought of using cpio, as I remembered that cpio has no embedded eof (a.cpio+b.cpio=cpio), but now I experiments and see that I was mistaken. Will try to establish a working solution. Thanks, Alon

Done[1]. Thanks! host-deploy: use cpio instead of tar for bundle transfer for some reason fedora-18/19 got tar out of base system, so we are forced to find some solution, although manual configuration is required anyway (repository, networking etc...). there was attempt to use python tar module, however this module has a bug when last block is empty, so it is not suitable for usage. cpio is alternative for fedora, however it is rightfully missing from other distributions as it is much less used. as we do not support hosts using different distributions, we are ok now. in future, we can use python self extract script, work already performed at: I1e5ddab9ae87979da7d7296c4f3c7ef08e21e903 at the price of complexity.

How about option 2.1: convince Fedora to reintroduce tar? It is ironic that Gnome is shipped by default, but not such a staple utility. Where in Fedora did this decision take place? Can it be undone? Is it commonplace these days among other distros to boycot tar? Dan.

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?

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. ----- Original Message -----

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?
