Well, when you don't rename /lib/tls to something else, you get "strange"
failures, i.e. things *almost* work. If that fixes the problem, don't go

Hmm, probably to debug this you need to do a
strace bash -c "true"
Assuming bash -c "true" gives the error.
In fact, the stracing starts after bash has finished his work, so it can't
help.
