Sure, you have some options. * Run NFS on a Linux system, XFS/JFS filesystem, export it to clients. * Use a different filesystem, OpenBSD supports FFS/FFS2, EXT2(..3 without journals), ISO9660, FAT(12/16/32), r/o support of NTFS, and network filesystems (NFS/AFS/Arla).
Finally, * Port said filesystem to OpenBSD natively, baring license problems, create your own implementation. Does that help? if not, then, nope, sorry. -Bryan.
