Are partitions independent of each other in linux in terms of fragmentation?

Question

File systems

Hello everyone,
There is a standard debian 6 server running video conversion tasks.
The fact is that at the time of conversion, temporary files are created (approximately 1GB - 4GB in size) which are then deleted.
I would like to move temporary files to tmp (to reduce fragmentation), but explain:
In my case,
df -H /tmp
Filesystem Size Used Avail Use% Mounted on
/dev/md2 2.0T 100G 1.8T 6% /
/tmp is in the root directory. So wouldn't fragmenting /tmp cause fragmentation in other directories (/var, /tmp, /etc...)?
Or are /var /tmp /home /etc independent of each other?
I would not want to store everything in RAM, the files are large.
I understand that it is possible to mount a separate partition for temporary files, but I would REALLY not want to manually configure this for each instance.

In the context of 1-4 giga files, worrying about fragmentation is completely stupid, it will not be there simply.
since you have everything on one partition, then the file system is the same, then the fragmentation is the same.
To be honest, I have no idea where you got such a strange idea from.
