You can remount a linux system on the fly like this:-

umount tmpfs

As many people know linux has a built in ramdisk – this is temporary memory and is very very fast (as it’s in ram). AS standard linux allocates 50% of your ram to this (don’t worry if you don’t use it linux uses all your ram anyway).

However sometimes you may decide the 50% is not enough (or is too much)
