The firmware of my NAS comes with a rather old version of
glibc, namely 2.5. In order to cope with some precompiled binaries linked* to
glibc 2.15, I would like to upgrade it. From some simple testing in a
chroot environment I learned simply adding the newer
libc-2.15.so and updating the symlink
libc.so.6 will yield an unusable system; probably due to
libc-2.15.so being linked to
ld-linux.so.3 in turn, which would of course also require the 2.15 version instead of the 2.5 one. But before I descend into too much trial and error,
what is the correct procedure to manually upgrade glibc?
*despite being linked "statically", they still dynamically link to glibc...
