[Solved]Update Download/Install Size

Sjoden · 2008-05-21 21:56:04

I just did a fresh install and did a pacman -Syu and the download size is 36mb, but the install size is 100mb. What is being compressed that much. This is from a 2008.3 RC3 core iso. Its updating things like kernel26 and mkinitcpio. Do those come really compressed, or do they create something larger when installed? I guess I never really paid attention to the install size...

Thanks,
Zack

Go to /var/cache/pacman/pkg, uncompress pkg.tar.gzs there and see for yourself.

I guess I was asking, is that normal? It just seemed odd to me. I didn't realize how compressed those pkgs were.

It is possible that some info is missing in the DBs. We just rebuilt them to contain all size info, but some members may be missing in the DBs you pulled from your mirrors

So... Some packages might not have had an 'installed size' value, so it wouldn't show up in pacman's "Total Installed Size: $$. MB"?

Yeah, but that could cause the problem in the other direction, like there :

There is also the fact that packages already downloaded dont appear in total download size. But if you are doing -Su, this does not apply.
There is also xdelta, but this is not used.
So basically, I can't explain what you are seeing.

I think it's pretty normal. For instance, kernel26's pkg.tar.gz is 25M and unpacked it's 93M. The compression ratio 25%-40% is understandable for files like documents and sources (and kernel package is a bunch of drivers (binary) and looots of header files - text documents). If you're curious, just try to compress some text documents (or something that has a lot of text in it). Other instances of this is stuff like tetex or texlive (also mainly textfiles).

Ah yeah, good point, it seems to be normal indeed
It would be interesting to see the ratios for every arch package.
Now that dbs were rebuilt, it should be very easy to do since pacman -Si has all the information now (yeah!)
