I am using http://www.debian.org/~aph/boot-floppies/19991118/bf-common.tar.gz.
untarred them into the common dir.
Starting from my potato installtion:

[06:50:53 bf]$ cd basetest/common/
[06:53:41 common]$ ls
base2_2.tgz  boot   dev          etc     home    lib  proc  sbin  usr
bin          cdrom  drivers.tgz  floppy  initrd  mnt  root  tmp   var
[06:54:09 common]$ su
Password: 
[06:55:00 common]# chroot .
rakefet:/# mount
rakefet:/# ps
Error: /proc must be mounted
  To mount /proc at boot you need an /etc/fstab line like:
      /proc   /proc   proc    defaults
  In the meantime, mount /proc /proc -t proc
Segmentation fault


Also note there are differences between your output and mine:
1) Your ps output gives a header line.
2) Without /proc my mount simply exit. No message like the one you are getting.
3) I am not getting the processes you get after /proc is mounted. Can it be 
that
I do not simulate an installation session correctly ?

And where is ash?
[07:04:27 common]$ ls bin/a*
bin/ae  bin/arch
[07:04:58 common]$
