>Description:
I'm trying to install a bootblock on a 1 gig seagate ST11200N,
giving partition a an offset of 1 cylinder for the bootblock.
When trying to write a bootblock with disklabel:

disklabel: boot overlaps used partition a
disklabel: boot overlaps used partition c
disklabel: cannot install boot program

Trying an offset of 2 doesn't seem to help.
>How-To-Repeat:
On an hp300, with seagate ST11200N drive, disklabel:

# /dev/rsd0c:
type: SCSI
disk: SCSI disk
label: SUN1.05 cyl 2036
flags:
bytes/sector: 512
sectors/track: 72
tracks/cylinder: 14
sectors/cylinder: 1008
cylinders: 2036
total sectors: 2052288
rpm: 5400
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # milliseconds
track-to-track seek: 0  # milliseconds
drivedata: 0 

4 partitions:
#        size   offset     fstype   [fsize bsize   cpg]
  a:   256032     1008     4.2BSD     1024  8192    16   # (Cyl.    1 - 254)
  b:   256032   257040     4.2BSD     1024  8192    16   # (Cyl.  255 - 508)
  c:  2052288        0       boot                        # (Cyl.    0 - 2035)
  d:  1539216   513072     4.2BSD     1024  8192    16   # (Cyl.  509 - 2035)

run disklabel -B sd0
