Yes, I saw this as well. Here's a temporary workaround until the patch makes it into the suppository: 1. Boot off kernel, single user 2. Mount everything: mount -a -t ufs (ignore the spooge about the root disk and fsck.) 3. TMPDIR=/var/tmp TEMPDIR=/var/tmp export TMPDIR TEMPDIR 4. Edit your configuration, change 'sd0a' to 'sd0s2a', and recompile your kernel. 5. mount /dev/sd0s2a /mnt 6. chflags noschg /mnt/kernel 7. install -c -m 555 -o root -g wheel -fschg kernel /mnt 8. reboot You should be right as rain afterwards, insulated from the current madness. Righteous burr under the saddle. Someone should have put out a bright neon sign e-mail two weeks before they checked this in. Possibly the low SNR in the current "Let's beat on Terry's stackable FS idea" caused me to miss it. >Similarly, my machine, whose root file system is on sd0s2a, claims >"changing root device to sd0s3a" during boot.
