But running certain additional commands on the live system when
DESTDIR is not set is not actually very standard ...

Why exactly ?

ldconfig does fixups for the live system. they're target and distro
dependent. oh, btw, according to the manpage, it's ELF specific.

Unless you're installing directly into the livesystem, the individual 
package doesn't even know when/how to do that (it would have to try
some guessing or need some clean interface). those things are naturally
out the individual package's scope, but belong into the package 
management.

Someone would have to support it. Either we have a generic interface
or the crosscompile folks need very special tweaking. This also
applies to people running the build on unprivileged users. Oh, and
guess what: gentoo's ebuild has such an an special tweaking.


So, for the vast majority of cases, running ldconfig directly in
an individual package's install rules is totally useless at best
or even completely broken.
