Again, if you're running -CURRENT, I strongly recommend backing out to the 3/12/98 revision of the kernel immediately if you are running anything with a later date. This will be my last note on this topic until I have determined that it is safe to use a more "Current" CURRENT. One last time - if you are running a CURRENT kernel built after this point, you are risking severe and unrecoverable damage to any locally-mounted UFS filesystems. If you do a "make world" and actually get through it with such a kernel (the odds are against this), you will be very, very fortunate if what you install as a consequence of that "make world" boots when you are done! The problem includes destruction of BOTH metadata (ie: inode, directory, etc) AND file data. The first will get fixed (for the most part) by FSCK. The second is COMPLETELY undetectable and absolutely will screw you if you run into it. Back out to 3/12 and it appears that you're safe from my testing here. -- -- Karl Denninger (karl@MCS.Net)| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly / All Lines K56Flex/DOV | NEW!
