onelfSingle-binary packaging for Linux

Pack any application into one executable file. No fusermount3, no visible temp dirs, runs invisibly.

One file, many tricks

Pack a binary and its libraries into a self-contained executable that runs everywhere a modern Linux kernel exists.

Invisible by default

Uses a private user+mount namespace plus FUSE so no mount ever shows up in the host, and kernel tears it down when the process exits. No fusermount3 dependency.

Cross-libc friendly

Run musl binaries on glibc hosts (or vice versa) with the bundled interpreter. No /tmp/.oi symlinks, no LD_PRELOAD trickery.

Delta self-update

Built-in zsync-based self-update. Just set the update URL at pack time and users run --onelf-update.

Reproducible

Same input with SOURCE_DATE_EPOCH set gives byte-identical output across machines.

Recipe-driven

Declarative onelf.toml makes packaging reviewable and shareable. Bundle + pack with one command.
