Description Matthew Galgoci 1999-07-09 17:30:53 UTC
I don't know if this is proper behavior or not,
but su seems to follow symlinks to their source.

However, when you exit the shell that you su to, it

eg:

[mgalgoci@skuzzlebutt linux]$ pwd
/usr/src/linux
[mgalgoci@skuzzlebutt linux]$ su
Password:
[root@skuzzlebutt linux-2.2.5]#
[root@skuzzlebutt linux-2.2.5]# exit
exit
[mgalgoci@skuzzlebutt linux]$ ls -al ../linux
lrwxrwxrwx   1 root     root           11 Apr 24 14:13
../linux -> linux-2.2.5
[mgalgoci@skuzzlebutt linux]$

The function getcwd(3) recurses backward to / from the current
directory in order to discover the path. When the shell is first
invoked (by su in this case), getcwd is invoked to find the current
directory. Henceforth, the arg of each cd command is used to save the
current directory. So, in your case, to restore the prompt, you
would need to do
	cd ../linux
or
	cd /usr/src/linux
to restore the prompt value.
