@zumbi, have you tested this properly?

[Héctor Orón Martínez]

If I did I do not remember, so long ago, but yes, something along the lines is needed.

[Andrej Shadura]

It needs absolute paths, dpkg-shlibdeps was failing because of this

[Héctor Orón Martínez]

If you do not know where sysroot is to be placed, then you can not use absolute path. If you have standard sysroot path it might work, but that path is architecture dependent.

I don’t think you’re supposed to call ldconfig without -r <sysroot> (or without running chroot), and it does read files relative to the sysroot. More than that, it doesn’t seem (from the ldconfig’s source code) relative paths work unless you actually chdir to /etc beforehand.
