<youpi> braunr: btw, after patching glibc and trying installing it, do you
  try rebuilding hurd against it? ext2fs.static often breaks due to details
<braunr> youpi: yes
<braunr> youpi: always
<youpi> ok, good :)
<braunr> i want the rootfs to benefit from it too :)
<youpi> heh :)
<braunr> and yes, there were issues that occurred only in the rootfs
<braunr> but because of the special early state, not because of static
  linking
