On: Picking Glibc Versions at Runtime

[ChocolateGod]

> In particular, if you need to replace not just glibc, but also a bunch of system libraries (pretty common case for complex apps), it's often easier to unshare(CLONE_NEWNS), followed by bind-mounting over new /lib64 and /usr/lib to override specific directories. This is much lighter than full-on containers

This is basically what Flatpak does.

[synergy20 → ChocolateGod]

is flatpak mainly designed for desktop gui? wish there are cli tools to help to develop non gui program with unshare

[voidbert → synergy20]

You can use bubblewrap, the sandbox Flatpak uses. However, the command lines will get pretty long.

[ChocolateGod → synergy20]

Yeh, exclusively.

For non-gui the closest thing is Docker/Podman.
