This is a shared hosting environment and I just noticed that only
1777 permissions (
/var/tmp also but they are besides the point here).
- Does that pose a threat to the security of the server? For instance, a system user might occupy the directories with useless junk and fill their disk quota;
- Given that the entire
/devdirectory is mounted on
devtmpfs, does that mean that everything will be flushed/deleted from the directory once a reboot takes place?
- What is the difference between
Here's what's currently mounted:
