strawberry on XO-1

[Mikus Grinbergs]

[ FYI.  I am _not_ asking for help;  I'm sharing my experiences. ]

Booted my XO-1 from an USB stick with build soas strawberry on it.

[Because I do not have any system on which mounting of a squashfs 
filesystem works, I have to use the rawhide version of the 
livecd-iso-to-disk script;  neither does livecd-iso-to-xo work, so I 
am unable to install builds distributed as .iso onto my XO's nand.]

Strawberry (F11-based) works;  but it is reproducibly stalling when 
doing a huge 'rsync'.  [Since the system then is unresponsive, I 
can't examine it.  My suspicion is that the system ran out of 
memory, despite having a swap partition active.]  The interesting 
thing is that on my XO-1, Soas2-20090622 (on which strawberry is 
supposedly based) runs the same 'rsync' without trouble.

Hi Mikus,

I think you should be about to use the XO image from
http://download.sugarlabs.org/soas/xoimages/ using the nand-copy
command to install it.

I have this same issue, and it's terribly annoying.  FYI, I hope we
can get filesystem lzma'd tarballs up (as dsd/OLPC are doing to XO 1.5
builds) somewhere soon to help with this type of thing.  As well we
can get pre-partitioned streams of bits that can be cat'ed to a USB
block device of 1, 2, or 4G so that the whole livecd-iso-to-disk.sh /
decide on drive partitions / etc. can be skipped for the XO build[1].

There isn't perhaps a kernel difference or significant memory pressure
difference, is there?  /me wonders aloud about the utility of cgroups
to limit the rsync's memory / cpu usage for diagnosis purposes.

1. For the XO build.  Only.  livecd-iso-to-disk.sh has a lot of
functionality for the non-XO build (home/root overlays,
MBRs/bootable-ness for a variety of BIOS/EFT targets, etc.) that I
don't think we want to decide for our learners/testers/deployers.
