5:29 p.m.
Systems such as Debian (and thus Ubuntu) operate with 64-bit programs in
/lib, with /lib64 a symlink to it: as a result, they apply a patch to
their glibc adjusting the default search path of the 64-bit dynamic
loader (only used if the library is not found in ld.so.cache) to look in
/lib, and instruct the 32-bit one to look in /lib32. Because fakechroot
is implemented via LD_PRELOAD, it ends up running the native dynamic
loader, and of course the appliance doesn't have an ld.so.cache early in
building. The effect of this is that, while building the appliance, you
are suddenly hit with an error like this:

`----
The 64-bit ld.so hunted in the initramfs's lib/ for 64-bit libraries to
link to... but in the appliance's lib/, 64-bit libraries are found in
lib64!
To work around this for good, explicitly set LD_LIBRARY_PATH
appropriately for the bitness of the current environment (and,
technically, for the distro of the appliance we're building, but that
just means a change to debirf is needed as well: this fix only handles
Fedora- appliance-on-Debian/Ubuntu-system, not vice versa).
(Note: it is quite possible that this is better implemented inside
febootstrap: but it works here.)
