I follow -current on an i386 at work and an amd64 at home, and rarely run into any problem which is not self-inflicted. So when I had a weird experience this weekend, I assumed it was my fault.
What happened was that after the usual sequence of [build kernel; reboot; build userland; reboot] the system complained that it could not fsck wd1j and dropped into single-user mode. wd1j is mounted on /usr/obj, and I thought that something in the last build had messed it up, so I ran "newfs wd1j" and got newfs: /dev/rwd1j: Device not configured "disklabel wd1" showed partitions d-i and k-p, but no j. I added the partition, ran newfs, and everything seemed fine. This afternoon I installed the i386 snapshot downloaded this morning (dated Jun 3 19:19) on the work pc, and after reboot it was missing the /usr/obj partition (sd0g in this case). Everything seems to be working fine on both computers, but I didn't expect the partitions to disappear. Did nobody else run into this "problem"? Or did everybody else who saw it thought it was too obvious to mention it to the mailing list? Emilio
