+ The file `pt_chown' is a helper binary for `grantpt' (*note
+ Pseudo-Terminals: Allocation.) that is installed setuid root to
+ fix up pseudo-terminal ownership. It is not built by default
+ because systems using the Linux kernel are commonly built with the

+ `--enable-pt_chown', you may build `pt_chown' and install it

+ additional security risks to the system and you should enable it
