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

---

SYNOPSISrofiles−fuse SRCDIR MNTPOINT

---

DESCRIPTIONCreating 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
