I want to change the stickbit permision of /tmp directory to -t.The problem is every time I reboot the permissions reset to 1777. How can I permanently change the /tmp directory to 0777 ?I have root permission to handle the init.d configuration, but I also need some guidance. My OS is Ubuntu Server 16.04.zeusbase@tiuque:/$ ls -la /...drwxrwxrwt   8 root root     4096 sep 27 09:20 tmp....
permanently change /tmp stickbit to -t
ubuntu;permissions;tmp
It is by design, the /tmp is a place where anyone can put (temporary) files, and only that user can remove/rename the file (the sticky bit is for this exact purpose).Do not change it, as it is used by many programs to keep data and would lead to a unstable condition if you remove the sticky bit and for some reason (e.g. unintentional deletion, bug) the file(s) from /tmp gets removed.Note that, on some systems /tmp is tmpfs (resides in memory), on some systems it is part of / (disk backed). On Ubuntu desktop, it is disk backed, and if you remove the sticky bit on it, you won't be able to initiate a session next time.
