NAME

       rofiles-fuse - Use FUSE to create a view where directories are writable, files are
       immutable

SYNOPSIS

       rofiles-fuse SRCDIR MNTPOINT

DESCRIPTION

       Creating a checkout from an OSTree repository by default uses hard links, which means an
       in-place mutation to any file corrupts the repository and all checkouts. This can be
       problematic if one wishes to run arbitrary programs against such a checkout. For example,
       RPM %post scripts or equivalent.

       In the case where one wants to create a tree commit derived from other content, using
       rofiles-fuse in concert with ostree commit --link-checkout-speedup (or the underlying API)
       can ensure that only new files are checksummed.

EXAMPLE: UPDATE AN OSTREE COMMIT

           # Initialize a checkout and mount
           $ ostree --repo=repo checkout somebranch branch-checkout
           $ mkdir mnt
           $ rofiles-fuse branch-checkout mnt

           # Now, arbitrary changes to mnt/ are reflected in branch-checkout
           $ echo somenewcontent > mnt/anewfile
           $ mkdir mnt/anewdir
           $ rm mnt/someoriginalcontent -rf

           # Commit and cleanup
           $ fusermount -u mnt
           $ ostree --repo=repo commit --link-checkout-speedup -b somebranch -s 'Commit new content' --tree=dir=branch-checkout
           $ rm mnt branch-checkout -rf
