Re: [fuse-devel] Disk based file systems in FUSE

[Dale E. E. <dem...@co...>]

Mrunal,

Hi.  I had a similar problem in the beginning.  Once I sort of
understood it, I found a FUSE version of cramfs (I believe it
was via the fuse homepage projects).  While it is only read-only,
it was very similar to what I was working towards and switch
to using cramfs as a skeleton project to build my own.  Almost
nothing remains of the original cramfs, but it is much better
than the examples for a disk filesystem.  You'll still have to
work out a ton of details and open your own FILE pointer to
the device etc....

Hope this help get you pointed in the right direction.
