-
- [ I've posted this to the linux-activists mailing list yesterday, but
- because the mailing list seems to out of order at the moment, I'm
- posting it on comp.os.linux now. Please understand that this is not
- an ordinary release but rather something highly experimental that
- may not work as intended and may be changed heavily (or completely
- disappear) in the future. ]
-
- A pre-alpha experimental version of IFS is available for anon. FTP
- on rudolf.ethz.ch as /incoming/ifs.0.tar.Z
-
- IFS implements a copy-on-write file system (similar to Sun's TFS)
- with the additional capability to mount "packs" of more than two
- directories. There's no Plan 9-style per-user FS space, sorry.
-
- IFS is relative to the 0.98pl6 kernel but it should be easy to use
- it with 0.98pl5 too. I haven't looked at earlier versions, so they
- might or might not work.
-
- This release has some major restrictions. Among them:
- - it has received very little testing yet, so be prepared that it
- might do something nasty to your system if you use it.
- - things like mkdir/rmdir, links, etc. are missing.
- - you can't run executables from it because bmap isn't supported.
-
- In its current state it isn't intended to do something usable for
- any real purpose but rather to illustrate the concept and to show
- one possible way to implement the "overmounting" mechanism.
-
- More information (and a lot more warnings :-) can be found in the
- README.
