The ldconfig service ("Rebuild Dynamic Linker Cache") updates /etc/ld.so.cache when it is
older than some preconfigured age. This increases boot time, especially when airootfs is
on a slower media, like a DVD-ROM drive or NFS. Since System Rescue doesn't change over time,
keeping the original file from release is fine.
