uutils coreutils v0.11.0

uutils coreutils — the GNU core utilities reimplemented in Rust — built for jailbroken iOS, replacing the GNU coreutils your bootstrap ships.

Which one do I download?

The architecture field names the bootstrap layout, not the CPU. Both packages carry the same arm64 binary.

your bootstrap	download
rootless (Dopamine, palera1n rootless)	wiki.qaq.uutils_0.11.0_iphoneos-arm64.deb
roothide (RootHide Dopamine)	wiki.qaq.uutils_0.11.0_iphoneos-arm64e.deb

Not sure? Ask the device: dpkg --print-architecture.

Requires iOS 15 or later. Or add the OwnGoal Studio repository and let your package manager pick.

This takes over coreutils — on purpose, and only if you ask

Installing it unpacks over the GNU coreutils in usr/bin: one multi-call binary with a symlink per utility beside it. The GNU coreutils package stays registered and keeps whatever this one does not ship, so apt, dpkg, Sileo and darwintools — all of which depend on it — are undisturbed.

The package declares Conflicts: coreutils so that no package manager installs it by accident. Resolving it from a repository would mean removing something apt and dpkg themselves need, and they will refuse. Installing it is a deliberate act:

sudo dpkg -i --force-conflicts wiki.qaq.uutils_0.11.0_iphoneos-arm64.deb

Do not run apt install on this .deb. apt treats a local file as an explicit request, honours the conflict, and removes coreutils first — which deletes rm, the one program dpkg insists on finding in PATH. The transaction then dies with your device holding no coreutils at all. If that happens, the GNU binaries are stashed in usr/libexec/uutils/gnu-backup; copy them back to usr/bin over SSH.

Removing it works normally — verified on device:

sudo dpkg --remove wiki.qaq.uutils                            # postrm puts the GNU binaries back
sudo apt-get install --reinstall coreutils system-cmds     # and dpkg's bookkeeping with them

The package's preinst stashes the GNU binaries before the takeover and its postrm copies them back the moment dpkg deletes this package's files, so rm is in place before anything needs it.

While it is installed, apt refuses to do anything else — that is the Conflicts doing its job, and it clears the moment you remove this package. Use dpkg -i / dpkg --remove in the meantime.

No fork(), no privilege escalation

Every child goes through posix_spawn(); fork(), setuid(), setgid() and setgroups() are defined to fail rather than imported, and the build refuses a binary that carries any of them. Children inherit the credentials the shell already had. Lowering still works — nice reduces its own priority, timeout signals the child's process group.

About this build

Upstream uutils/coreutils@bf65901, built from the feat_os_unix_musl utility set, plus the patches in patches/: timeout spawns without a pre_exec closure; fork() and the credential syscalls are denied; chroot is dropped; and the xattr crate is taught that iOS has Darwin's extended attributes, without which cp -a fails with unsupported platform.

Not included: chroot (needs root and the denied syscalls), stdbuf (its helper library would have to be injected into a platform-signed process), chcon and runcon (SELinux). getent is not a uutils utility — the GNU package carried Procursus' build of it, so a small POSIX-sh stand-in ships in its place for the passwd, group, hosts, services and protocols lookups the shells do.
