untimes, and portable GUI rendering libraries could be. CoreOS - which was for creating minimal host images that host containers - is now Fedora Atomic is now Fedora Atomic Desktops and rpm-ostree. Silverblue, Kinoite, Sericea; and Bazzite and Secure Blue. Secureblue has a hardened_malloc implementation. From https://jangafx.com/insights/linux-binary-compatibility : > To handle this correctly, each libc version would need a way to enumerate files across all other libc instances, including dynamically loaded ones, ensuring that every file is visited exactly once without forming cycles. This enumeration must also be thread-safe. Additionally, while enumeration is in progress, another libc could be dynamically loaded (e.g., via dlopen) on a separate thread, or a new file could be opened (e.g., a global constructor in a dynamically loaded library calling fopen). FWIU, ROP Return-Oriented Programming and Gadgets approaches have implementations of things like dynamic header discovery of static and dynamic libraries at runtime; to compile more at runtime (which isn't safe, though: nothing reverifies what's mutated after loading the PE into process space, after NX tagging or not, before and after secure enclaves and LD_PRELOAD (which some go binaries don't respect, for example). Can a microkernel do eBPF? What about a RISC machine for WASM and WASI?

Python's manylinux project specifies a number of libc versions that manylinux packages portably target. Manylinux requires a tool called auditwheel for Linux, delicate for MacOS, and delvewheel for windows; Auditwheel > Overview: https://github.com/pypa/auditwheel#overview : > auditwheel is a command line tool to facilitate the creation of Python wheel packages for Linux (containing pre-compiled binary extensions) that are compatible with a wide variety of Linux distributions, consistent with the PEP 600 manylinux_x_y, PEP 513 manylinux1, PEP 571 manylinux2010 and PEP 599 manylinux2014 platform tags. > auditwheel show: shows external shared libraries that the wheel depends on (beyond the libraries included in the manylinux policies), and checks the extension modules for the use of versioned symbols that exceed the manylinux ABI. > auditwheel repair: copies these external shared libraries into the wheel itself, and automatically modifies the appropriate RPATH entries such that these libraries will be picked up at runtime. This accomplishes a similar result as if the libraries had been statically linked without requiring changes to the build system. Packagers are advised that bundling, like static linking, may implicate copyright concerns github/choosealicense.com: https://github.com/github/choosealicense.com From https://news.ycombinator.com/item?id=42347468 : > A manylinux_x_y wheel requires glibc>=x.y.
