Well, I finally got around to modifying my PogoPlug. While following the install procedures I got to step 8:
$this->bbcode_second_pass_code('', '
Download and install Arch Linux ARM:
cd usb
wget http://archlinuxarm.org/os/ArchLinuxARM-armv5te-latest.tar.gz
tar -xzvf ArchLinuxARM-armv5te-*.tar.gz # This will take a long time
rm ArchLinuxARM-armv5te-*.tar.gz
sync # Takes a while when using a flash drive
')
And decided to optimize it just a tad:
$this->bbcode_second_pass_code('', '
cd usb
wget -O - http://archlinuxarm.org/os/ArchLinuxARM-armv5te-latest.tar.gz | tar zxvf - # This will take a fairly long time
sync # Takes a while when using a flash drive
')
The '-O' is a capital 'o' not a zero.
This speeds up the install, as there is only one write to the thumbdrive, and the tar doesn't have to read from the thumbdrive, and you don't have to delete the archive. Using the install current today (17Dec13) my install weighed about 480M, so you should be able to do the install, this way, on a half gig thumbdrive.
Tom.
