/hold
depends on #1057 . We don't have mkdir command now.

[huww98]

We still have some more deps to be eliminated:

• losetup
• growpart
• mkdir
• chmod
• grep
• tail
• blockdev
• nsenter
  • udevadm
  • iohub-vfhp-helper
  • get_dbfs_mount_path
  • dbfs_get_home_path.sh

[huww98]

/unhold
since I've added mkdir.

[huww98]

should rebase after #1102 got merged. And remove blockdev

[huww98]

#1057 is merged, dropping mkdir
