quick grub question

[Robert Ross]

Hello,

A friend and I are installing linux on a flash device, and currently we're
using GRUB.  One of the reasons we chose not to use LILO was that by
default it writes to the device on every boot; these flash devices are
only good for so many writes.

We went looking through the FAQ and other sources to determine if GRUB
stores anything on the disk at boot time, and we didn't find anything that
indicated that it did; however, we want to make sure.

Can an informed person tell me definitively that GRUB isn't writing
anything when I boot?

Thanks so much,

Rob
