OS X supports UFS? Which UFS? As in FFS (which open/net/free use)? That's pretty cool but I figured OS X would have some nifty brand new filesystem.
And no, NetBSD can't use ext2fs as /. Using ext2fs for /home is a good idea, I use it on my system with Linux and FreeBSD. Only problem is that FreeBSD can't fsck ext2fs but I think NetBSD can (I haven't gotten NetBSD to mount any non-bsd partitions yet, I could probably get it too, but I don't have the time to mess with it yet). Well, I at least know for sure that NetBSD supports ext2. HFS support in linux doesn't seem too bad, though I keep my macos partition mounted read-only unless I must write to it for some reason. I had a BAD experience where linux messed up an hfs partition but this was back with a 2.0 kernel and I believe hfs support was refined quite a bit in the 2.2 series and here we are at 2.4. And I have worked with my HFS partition somewhat with read/write using 2.2 kernels and 2.4 with no trouble at all. Linux can mount UFS/FFS partitions, and read-write support is available. But I STRONGLY suggest mounting FFS/UFS partitions read-only, you can damage the filesystem, and in fact, I have. I've not damaged a BSD file system, though, if I open a file in a text editor it tends to corrupt the file (like half the file will be gone). I have killed solaris filesystems through linux though... Which is of course a UFS, and I don't know really much at all about OS X's file system. You've been warned. Hope that info was helpful. -Cameron On Tue, 22 May 2001, Ethan Benson wrote: > On Tue, May 22, 2001 at 12:57:35PM -0700, Matt Brubeck wrote: > > Hi.
