Can I delete Tmpfs Linux?
Edit: You can’t empty tmpfs, but you can remove files and folders from /tmp. When you have mounted tmpfs at /tmp, you can treat it as any directory in the filesystem. If you know which files and folders that’s not needed anymore, you can just remove them in the same way as you remove other files from the filesystem.
Does Tmpfs use RAM?
When you do put files in the tmpfs, that will use memory, but only as much as the files you put into the tmpfs. If you then don’t touch those files for a long time and the system needs to use the RAM more than it needs to keep them in buffer cache, those files will actually get backed from swap instead of RAM.
Does Tmpfs use swap?
The TMPFS file system allocates space in the /tmp directory from the system’s swap resources. This feature means that as you use up space in the /tmp directory, you are also using up swap space.
