Currently, the cgroupfs-mount package only mounts a cgroup v1 hierarchy, but v1 is considered legacy and obsolete, while v2 has been around for a while now, and is required by some packages (e.g. podman whines about v1). cgroupfs-mount has not had a release in almost 8 years now, and only the occasional commit since then and until more than 3 years ago. It's not going to evolve... Add a new package with a simple-enough sysv startup script, that mounts the cgroup v2 hierarchy filesystem. For systemd, there's nothing to do, as systemd handles the mount by itself. Since both cgroup v1 and v2 use the same mountpoint, we can't have both enabled at the same time, and thus we restrict the v2 to be hidden when v1 is enabled (quite a few packages select the v1; changing those would require that they be validated against v2 first...) Note that, due to limitations in Kconfig, cgroupfs-v2-mount will appear indented below cgroupfs-mount, because it has a (negative) dependency on it. This spurious indentation is unfortunate and annoying, but benign; fixing that would require breaking the dependency with a random Kconfig symbol, which we don't have, and which we decided not to introduce just for this one use-case (well, there's host-gnupg and host-gnupg2 that have the exact same issue, but meh...)

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
