Re: I/O Error on Readonly Filesystem
Sorry. that's Powerpoint. It automatically capitalizes the first word of every line. It's all lowercase. sync just makes sure all the buffers have been written to disks. They say there are three signs of stress in your life. You eat too much junk food, you drive too fast and you veg out in front of the TV. Who are they kidding? That sounds like a perfect day to me!

Re: I/O Error on Readonly Filesystem
This is a well-known problem in sharing r/o disks among VM linux images. The cure is a fairly simple one. Go to Mark Post's Linuxvm.org site to the SHARE presentations at http://linuxvm.org/present/ and look down for the San Francisco SHARE last August. My paper number 9341 has the answer on slide 16. At least, it cures this exact error for us! Hope this helps! They say there are three signs of stress in your life. You eat too much junk food, you drive too fast and you veg out in front of the TV. Who are they kidding? That sounds like a perfect day to me!
