Does downloading in /mnt affect the overlay?

[Dantes]

I could not find any information on this, so I'm pretty sure I'm missing something.

I have installed a SquashFS image and I want to mount an internal drive as /mnt/storage. The overlayFS is active on the root / . Does mounting a block device on /mnt/storage affect the overlay other than the directory in /mnt ?

If I install transmission and start downloading, does this affect the overlay ?

Thank much,

Dantes

Mounting something in /mnt/storage should be safe. At least I have never noticed anything on /overlay when I add something to USB stick at /mnt/sda1

Thank you very much, lets see if I can reproduce

You were correct, /mnt is unaffected, yay!

I think my problem was the cache directory in /opt/transmission
That might have been slowly filling the overlay.
