OK, now I get it. I have another chroot for f20, which is after the
/bin -> /usr/bin transition, that works because it doesn't need any
If you use a login shell (eg, "chroot /bb bash -l" instead
/bb bash"), the dotfiles that will be sourced will set the appropriate
Sadly, no, not without editing them. The only pathmunge()'ing I see is
