OSTREE CREATE-USB(1)

NAME
ostree-create-usb - Put the given refs on an external drive for P2P distribution.

SYNOPSIS

ostree create-usb [OPTIONS...] {MOUNT-PATH} {COLLECTION-ID REF} [COLLECTION-ID REF...]

DESCRIPTION

This command creates a repository in MOUNT-PATH and pulls the given REF(s) into it so they can be found and pulled from (perhaps by another computer that's offline). See ostree-find-remotes(1) for more information on P2P distribution.

In order for ostree to pull refs from a mounted filesystem (such as a USB drive) the repo must be in a standard location. Specifically, subdirectories of .ostree/repos.d are checked, then .ostree/repo, ostree/repo, and var/lib/flatpak/repo are checked. By default ostree create-usb uses .ostree/repo, but if you specify another location using --destination-repo a symbolic link will be created for you in .ostree/repos.d.

This command will regenerate the summary file in the destination repo so that it stays accurate, so you shouldn't try to use summary signatures in the destination repo. This shouldn't be a concern because clients that support pulling from USB mounts use signed per-repo and per-commit metadata instead of summary signatures.

This command relies on the summary file in the source repo, so you may want to run ostree summary -u before running this command.

OPTIONS

--disable-fsync
    Do not invoke fsync().

--destination-repo=DEST
    Create the repository in DEST under MOUNT-PATH, rather than the default location.
