Before diving too deep into namespaces we also discussed contacting the people from oe and pseudo and checking whether the problems come from ld so which you might patch with a custom library in ldpreload.

As we just discussed, step 1 fails already since multistrap calls
dpkg --configure and this calls ldconfig.

Since ldconfig is static, this will never work.

(This is about fakeroot, but it also uses LD_PRELOAD)

As we discussed
* I will analyze how bitbake and wic use pseudo
* Have a closer look if this can be solved by user namespaces
