Hi!
I'm having the following problem under Minix/ST.
I don't know if it applies to PC 1.3.

The problem is as follows:
If I mount a file system on a dir which itself also is on a mounted
file systems, some programs fail, since they don't seem to recognize
pathnames properly.

The problem can be reproduced by:
boot using the original floppy.
insert root disk.
insert /usr1 disk on request.
log on as root
cd /usr
mount something on say the ast dir
(e.g. in my case: /etc/mount /dev/hd3 ast)
go into the newly mounted filessystem
(e.g. cd ast/usr)
do a pwd.
When I did this I expected a pathname /usr/ast/usr.
Instead I got /ast/usr

The same problem occurs after applying the recently posted patches to 
use the disk as root fs, when mounting another partition.

I think the problems are related to pwd, and file systems that are not
mounted in /, but I'm not really sure.
Anyone any suggestions?
