Subject: Re: UDF filesystem image with Write-Once UDF Access Type

Hey all

I'm a bit pressed for time these days, so I won't be able to do any 
tests any time soon.

Also have to admit that I lost interest in UDF a bit, since we ended up 
looking towards hardware solutions for write-protections instead.

But when/if mkudffs includes an option to create a write-once / 
read-only filesystem while adding files to it at the same time (because 
how else am I gonna put files onto my read-only filesystem?), then it 
might become interesting again.
