>Description:
Gpart when cloning does not transfer label name


I increased the size of the pool by adding a larger disk ada1:
#gpart backup ada0 > ada0.backup
#ee ada0.backup  # fix name
# cat ada0.backup
GPT 128
1   freebsd-boot       34     1024 boot-1
2   freebsd-swap     2048  2097152 swap-ada1
3    freebsd-zfs  2099200 14677983 system-ada1

#gpart restore ada1 < ada0.backup
#gpart resize -i 3 ada1

# gpart list | egrep 'name|^   type|label'
Geom name: ada0
   label: boot-0
   type: freebsd-boot
