inode number -> pathname? (4.2BSD)

[Andrew Klossner]

[]

	"If it were possible to set the current working directory to a
	given inode and device, then pwd would give you the answer.
	All the permission information, and even the bit denoting
	whether or not this inode refers to a directory is stored in
	the inode, and can easily be checked in such a call."

The permission information is distributed throughout the path to the
directory.  If /usr/fred is mode 0700, then the fact that
/usr/fred/sources is 0755 should not be construed as sufficient reason
to allow another user to chdir to /usr/fred/sources.
