Re: RFC [0/2] test-in-container

[Joseph Myers <joseph at codesourcery dot com>]

Suppose /bin/sh uses a library whose system location is the same as the 
location where the glibc-under-test would install something in the chroot.  
(For example, say it uses /lib/libc.so.6 and the glibc-under-test would 
also install that file.)  Do you keep the two copies separate - keep sh's 
libraries somewhere else in the chroot so the new glibc's don't overwrite 
them?  Even for native testing, you can't assume that the two have the 
same ABI - consider various cases where hard-float and soft-float have 
different ABIs but use the same library paths, for example.

What do in-container tests actually require /bin/sh to be able to do?  Is 
it more than just e.g. "split a command on spaces and execute it"?  (I'm 
wondering if a trivial /bin/sh implementation like that would suffice 
inside the chroot.)
