-------------------------------------------------------------------
[~yunta] Why do we see this warning on CI of every modified image:
??WARNING: attempted to load jemalloc from
/usr/lib/x86_64-linux-gnu/libjemalloc.so but the library couldn't be found.
glibc will be used instead.??

> ARM images are not using jemalloc because LD_PRELOAD is hardcoded to use an
> x64 path, causing this error:
> {noformat}
> ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libjemalloc.so' from
> LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
> {noformat}
> Right now docker-entrypoint is using this:
> {code:sh}
> maybe_enable_jemalloc() {
> if [ "${DISABLE_JEMALLOC:-false}" == "false" ]; then
> export LD_PRELOAD=$LD_PRELOAD:/usr/lib/x86_64-linux-gnu/libjemalloc.so
> fi

> {code}
> I propose we use this instead:
> {code:sh}
> maybe_enable_jemalloc() {
> if [ "${DISABLE_JEMALLOC:-false}" == "false" ]; then
> # Maybe use export LD_PRELOAD=$LD_PRELOAD:/usr/lib/$(uname
> -i)-linux-gnu/libjemalloc.so
> if [[ `uname -i` == 'aarch64' ]]; then
> export
> LD_PRELOAD=$LD_PRELOAD:/usr/lib/aarch64-linux-gnu/libjemalloc.so
> else
> export
> LD_PRELOAD=$LD_PRELOAD:/usr/lib/x86_64-linux-gnu/libjemalloc.so
