Hello,

I've csup'ed about 1 hour ago (previous csup was few days back),
recompiled kernel and slice names changed from ad0s5 to something like
ad0s3s1, etc.
But in /dev I found only 3 levels of slices:

# ls /dev/ad0s3*
/dev/ad0s3      /dev/ad0s3s1    /dev/ad0s3s2    /dev/ad0s3s2s1  /dev/ad0s3s2s2

>From this list only 2 slices contains real FS: ad0s3s1 and ad0s3s2s1
Before reboot I had 4 logical disks...

Here is output of fdisk:

# fdisk ad0

# fdisk ad0s3s2s2
fdisk: could not detect sector size

Data on unaccessible partitions is not critical, so for a while I
wouldn't change anything if you need some additional information.

Some additional information:

# grep -i geom /usr/src/sys/i386/conf/HEAD
options         GEOM_PART_GPT           # GUID Partition Tables.
options         GEOM_LABEL              # Provides labelization
