Problem solved: I filled the partition with /tmp on it, so nothing

Interesting. I hadn't considered that a full /tmp partition would do
it. I don't have it on a separate partition on any of the systems I
run, so this never came up. I'll be tucking that bit of info away for
future use.
/tmp can fill up even if it's on the root partition...of course,
if that happens, then your root partition is full, too.

Personally, I don't like ANY unnecessary file I/O on my root
partition, so /tmp always gets its own partition
I/O is still I/O that has to be handled by the _disk_ not the
_partition_, so it matters not if /tmp is on it's own partition unless
it is also on a different disk.

So if the /tmp directory is corrupted, and it is on its
own partition (and therefore, a separate filesystem),
this corrupts the root filesystem how, exactly?

You weren't talking about corruption but only disk I/O.

A filesystem can't get corrupted if there's no write
activity on it.

No, they're directly related.

> Disk I/O affects all partitions on the disk not just one.

the overall wear of read/write head and it's controller arm
is effected, along with the data on the particular
partition/filesystem being written to.

Remember, it's a physical device doing a physical
activity...MODIFYING the data at a specific location
on the physical platter(s).

the / partition due to head movement etc.

But that corrupts the / partition how, exactly?

You're not an engineer, are you?
