If you want to achieve all that *at once*, then yes, it does. > i just want to have a filesystem (growisofs can do that) > and in that filesystem i want to write to one continuos file > (of which i dont know the size untill i am done (would it be that > bit requireing write access?)). Even though it's *theoretically* possible to arrange for this with ISO9660 (i.e. reserve some place in the beginning of media, burn down input stream till you know how large is it and *then* burn volume descriptor and directory structure), no such implementations are available. The only *available* way to realize all of the above is live file system, which implies kernel support. > i guess i can give up the "filesystem and filenames" bit, Give up the compress part instead and deploy growisofs -M with Ohly's patch. There're certain limitations too, most notably inability to restore hard-links (I have rockrestore in my TODO list, which would restore rock-ridge volume with hard-links, but I can't make no promises).
