<div dir="auto">Thanks James & Nathan. This "model" XO-1 has 256MB of disk available on fresh install of 13.2.8, which never falls below 240MB when trying many different ways to install the "7+ MB" TuxMath.<div dir="auto"><br></div><div dir="auto">So I'm surely doing something wrong, and wi<span style="font-family:sans-serif">ll keep working on it this week, until I rediscover something like the reliable TuxMath install recipe we had for Haiti earlier.</span><br><div dir="auto"><br></div><div dir="auto">Then, trying to install the "142+ MB" GCompris will be a different story of course, given its OS library needs installing Tux Paint etc alongside, which may require me deleting the 70+ MB /home/olpc/Library (and other /tmp /var/tmp or swap adjustments?

laptop has been used for a bit. Fresh install gets the best space.<br>
<br>
(Because JFFS2 compresses data when writing, it cannot know how much<br>
free space is available, as because it depends on how compressible the<br>
data is. So JFFS2 provides an estimate, and the estimate is<br>
pessimistic, and yum takes it at face value.)<br>
<br>
Yes, one XO-1 may show different space to another XO-1 freshly<br>
installed.<br>
<br>
(Because NAND may have bad blocks that are skipped by JFFS during<br>
reflashing. You will have noticed these as differently coloured.<br>
Good chance of more bad blocks as the laptops age.)<br>
<br>
Yes, removing files apart from Activities and Library won't fix space.<br>
<br>
(Because olpc-update keeps a hard link mirror of the filesystem in<br>
/versions, and your changes to removing files won't remove them from<br>
the copy.)<br>
<br>
Yes, customising the operating system is really time consuming; we<br>
have instead provided the tools for remastering the operating system,<br>
and these tools are easy to use. Adding .xo and doing yum installs<br>
are supported. See OS_Builder on the Wiki.<br>
<br>
If you lack resources to do this, then I can assist to a limited<br>
extent, as I did for Haiti in January last year. Additional benefit<br>
of using me is that the build may be signed, which installs using the<br>
four game key method without having to create deployment keys.<br>
<br>
Workaround for yum lack of space is to use .rpm files directly. Also<br>
much faster.<br>
