File name with a comma fails to mount

[mobedoor]

I came across an issue mounting a dwarfs image with a comma in the file name.

dwarfs merge,t.dwarfs test
fuse: unknown option(s): `-o t.dwarfs'

Works on my system:

$ ll merge,t.dwarfs               
lrwxrwxrwx - mhx users 28 Dec 16:12 merge,t.dwarfs -> arpa.dwarfs
$ dwarfs merge,t.dwarfs mnt
$

It seems like something is trying to split-by-comma and treat the second part as a FUSE option.

From the log, I'm assuming you symlinked arpa.dwarfs to merge,t.dwarfs. That works fine for me as well. It's only when the original file has a name containing comma that the issue arises

Remove symbolic link and rename file

rm test,t.dwarfs
mv merge.dwarfs test,t.dwarfs

Create new symbolic link

ln -s test,t.dwarfs merge.dwarfs

Unmount test directory

umount test

Attempt to mount merge.dwarfs (fails with same error)

dwarfs merge.dwarfs test

Thanks! This was indeed introduced by 24d3acb when passing -ofsname=<image> to FUSE.

Thanks for the prompt fix.
