Where did you get the code? Several years ago, we - Kazuto and I - made the filesystem just for magazine readers. We designed it as simple as we could, as it was a sample filesystem to explain about the design and the implementation of linux filesystems. I guess there may remain many things to do about it: - To support tar.gz and tar.bz2. I guess this should be done in a compression device, which might be md layers or a loop device itself. - It may be better if you can make tarent objects free-able while the filesystem is mounted. - It may be possible to implement append mode. A new file can be appended to the filesystem. We're expecting you to do a good job. > oh,sorry.it's a readonly filesystem now.i will try to make it writeable. > but i use tar file as loop device. > > by the way,if we mount an iso file it's a readonly filesystem too. > i think maybe we should do something on the loop device to support > this kind of write. > > On Sun, 07 Nov 2004 07:13:51 +0000, James Tabor > wrote: > > andyliu wrote: > > > > > > > hi > > > > > > let's think about the way we access the file which contained in a tar file > > > may we can untar the whole thing and we find the file we want to access > > > or we can use the t option with tar to list all the files in the tar > > > and then untar the only one file we want to access. > > > > > > but with the help of the tarfs,we can mount a tar file to some dir and access > > > it easily and quickly.it's like the tarfs in mc. > > > > > > just mount -t tarfs tarfile.tar /dir/to/mnt -o loop > > > then access the files easily. > > > > > > it was writen by Kazuto Miyoshi (kaz@earth.email.ne.jp) Hirokazu > > > Takahashi (h-takaha@mub.biglobe.ne.jp) for linux 2.4.0 This address is no longer usable. > > > and i make it work for linux 2.6.0. now a patch for linux 2.6.10-rc1-mm3 > > > > > > the patch is to big to send it as plain text, so i can only send it as > > > an attachment > > > > > > thanks > > > > > Wow!
