NAME

6       rofiles-fuse - Use FUSE to create a view where directories are
7       writable, files are immutable
8

SYNOPSIS

10       rofiles-fuse SRCDIR MNTPOINT
11

DESCRIPTION

13       Creating a checkout from an OSTree repository by default uses hard
14       links, which means an in-place mutation to any file corrupts the
15       repository and all checkouts. This can be problematic if one wishes to
16       run arbitrary programs against such a checkout. For example, RPM %post
17       scripts or equivalent.
18
19       In the case where one wants to create a tree commit derived from other
20       content, using rofiles-fuse in concert with ostree commit
21       --link-checkout-speedup (or the underlying API) can ensure that only
22       new files are checksummed.
23

EXAMPLE: UPDATE AN OSTREE COMMIT

25           # Initialize a checkout and mount
26           $ ostree --repo=repo checkout somebranch branch-checkout
27           $ mkdir mnt
28           $ rofiles-fuse branch-checkout mnt
29
30           # Now, arbitrary changes to mnt/ are reflected in branch-checkout
31           $ echo somenewcontent > mnt/anewfile
32           $ mkdir mnt/anewdir
33           $ rm mnt/someoriginalcontent -rf
34
35           # Commit and cleanup
36           $ fusermount -u mnt
37           $ ostree --repo=repo commit --link-checkout-speedup -b somebranch -s 'Commit new content' --tree=dir=branch-checkout
38           $ rm mnt branch-checkout -rf
