A customer of mine for our embedded products was relating to me his worries about using Compact Flash with Linux. He claimed that Linux (in ext2, ext3, possibly others) filesystems, when mounted read/write, will write to the filesystem every-time a file is read, in order to update some time-stamp (atime?) I don't believe him, but since I wasn't sure, i couldn't argue with this. Is this true?
I think this is true, because you can pass a non-default option to "mount" when mounting a filesystem.
From the mount man page:
noatime
Do not update inode access times on this file system
(e.g, for faster access on the news spool to speed up
news servers).So, you can probably argue to your customer that he should be mounting with the noatime flag :)
Hope this helps
