I think Reiserfs is used on a lot more than squid servers. For them,
80% of files don't move for long periods of time is the usual industry
statistic.

I wonder if anything like this exists already...
Maybe it would work if you could provide moderated ssh access.

Hello,
suppose pseudo files, file-as-directory are on my r4 partition and are usuable.
Does namesys' vision allow things like storing image thumbnails "inside the file

Example using jpgtn (jpgtn creates thumbnails of jpg files)
// create 150px thumbnail
$ jpgtn -s 150 -H test.jpg

Does the repacker use fsync? I wouldn't expect it to.
Does fsync benefit from a properly packed FS? Probably.
Also, while I don't expect anyone else to be so bold, there is a way
