There is a solution for 1: Don't use the newer `mk2efs' utility. This is what I did: I needed to install RedHat 6.2 (that has a newer kernel which reads disklabels properly). I began with the RedHat 5.2 installation CD, made partitions, made an ext2fs file-system, and then began off with RedHat 6.2 installation (and told it NOT to format my partitions). Now, FreeBSD-3.4 reads from ext2fs fine. (Phew!) I suppose the problem has been solved with FreeBSD-4.1 etc. I use Linux to mount my UFS partitions. But, they get mounted ro. I configured the kernel to allow (experimental) rw access to UFS, and occasionally use it. I didn't want to risk losing my data. What has your experiences been with rw access to UFS ?
