I tried the root.bin at
http://people.debian.org/~aph/debian/dists/potato/main/disks-i386/2.2.22-2001-04-02/images-1.44
and was able to reproduce the above failure. However, when I ran
the busybox id included on that root.bin, it succeeded. It
appears to be busybox version 0.43, which contained its own files
for parsing /etc/passwd and did not rely on the name service
switch. More recent versions of busybox allow you to choose
between this homegrown implementation and the name service switch
support. My guess is that it somehow switched to the nss version,
which fails due to missing libraries and configuration files. So
this bug should probably be reassigned to busybox, with a request
to build it with USE_SYSTEM_PWD_GRP=false.
