the importance of providing swap space
Helped a friend install os8 on his XO-1. When we got done, he decided to enter the command 'yum install gparted'. Yum failed with a not enough memory error. I happened to have an SD card with me that had a swap partition defined on it. The XO's SD slot was already in use, so I attached an USB card reader (with my card in it), and issued the appropriate 'swapon /dev/...' command. Now he could issue 'rpm -e gparted' and then 'yum install gparted' again. This time, yum was successful. The moral: Things can be done if swap space is present that cannot be done if swap space is not present. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: the importance of providing swap space
It seems you got lucky, the most common behavior is for it to crash. I've been an advocate of SWAP for the XO since I got one, even things like browsing become many times faster. It becomes even more important on the XO OS because it seems to take up anywhere from 30-80MiB more than a similar distribution. Some users of DebXO have reported that they don't need swap and I've also noticed that memory requirements on my custom built xfce Gentoo are much lower. I can get Firefox open with 3-5 tabs and stay below 70MiB whereas on the Fedora, even with XFCE, It usually goes up to more than 120MiB. Open a PDF and you're done.

Re: the importance of providing swap space
I happened to have an SD card with me that had a swap partition defined on it. The XO's SD slot was already in use, so I attached an USB card reader (with my card in it), and issued the appropriate 'swapon /dev/...' command. I'd suggest a small enhancement: that when a removable medium with a valid swap partition is plugged in, start swapping to it immediately. That would cause a problem when trying to remove it, though, since Linux doesn't provide a dismount all partitions in preparation for ejecting operation in the GUI. Perhaps this is one area where Sugar could improve on the general Linux GUIs. John ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
