Ensure locating libnss* files doesn't fail on merged-usr systems
Since debootstap v1.0.102 it defaults to --merged-usr, creating
/{bin,sbin,lib}/ symlinks pointing to their counterparts in /usr/
Debian/buster provides debootstrap 1.0.114 and therefore defaults to
--merged-usr as well. If the grml-live build environment
is based on Debian/buster we get this as default.
Inside backend/initramfs-tools/live.hook we have:
| for _SHLIB in $(find /lib -name 'libnss_dns.so.*' -o -name 'libnss_files.so.*')
| do
| copy_exec "${_SHLIB}"
| done
So if /lib is a symlink to /usr/lib (with merged-usr), then the `find
/lib ...` won't find any files (since it doesn't follow the symlink).
This change fixes this behavior.
