- I think what Mike meant was taking a disk with a filesystem created under
- 4.1.2, attaching it to a 4.1.1 Sun and mounting said filesystem there. There
- were some changes at 4.1.2, which I believe were in support of being able to
- determine that the filesystem is "stable". But I think it was just using some
- formerly unused bits in some already-reserved space, and most likely 4.1.1
- simply won't pay any attention to them.
-
- If the release notes don't go out of their way to say that it won't work,
- you're probably OK. The best way to check might be to mount the filesystem
- read-only the first time and see if anything complains.
-
- Alternatively, is there any reason why you couldn't simply mount it through
- NFS from the 4.1.2 system it's presumably on now?
