rofiles-fuse: Handle operations on the root (886 bytes, patch)
2016-02-24 11:17 UTC, Alexander Larsson 		accepted-commit_now Details | Review

Description Alexander Larsson 2016-02-24 11:07:43 UTC 
I can't chdir into the root of the mount:

$ mkdir x
$ mkdir x/y
$ mkdir z
$ rofiles-fuse x z
$ cd z
bash: cd: z: No such file or directory
$ cd z/y
$ cd ..
bash: cd: ..: No such file or directory
$ cd ../..

Here is the syscall failure:

23483 stat("/home/alex/x/z", {st_mode=S_IFDIR|0755, st_size=6, ...}) = 0
23483 chdir("/home/alex/x/z")           = -1 ENOENT (No such file or directory)

Not sure whats causing the failure.

rofiles-fuse: Handle operations on the root

ENSURE_RELPATH breaks when path is "/". In that case we need
to return "." instead of "".

Figured it out...
