There is also read/write support for JFS in the Linux kernel. eComStation has supported booting from JFS for about 10 years now. There are plenty of reasons not to run OS/2 these days, but I don't believe file system corruption has been a real risk since HPFS was superceded. I ran OS/2 2.1 & Warp 3 in the mid '90s and have looked at eComStation briefly. To me, the biggest thing in eComStation that sticks out now compared to modern operating systems is lack of multiuser support in the kernel. Even Microsoft had this in the first versions of Windows NT. In OS/2 & eComStation, you're basically running everything as "root", so there is very little to prevent a rogue program or user error from deleting system files and rendering your system unbootable. There could well be addons to reduce this risk, though. Regards Andrew
