Talk:Burning the Installation Media
From PC-BSD Wiki
helpful for USB sticks
- no need to zero the entire thing, can be a limited zero that will be as effective-
dd if=/dev/zero of=/dev/usbstick bs=1024 count=10
- If KDE or Dolphin or Device Notifier succeed to mount a USB stick but you cannot unmount it, even when you are not actively using it, switch to root and then issue the shell command.
- A USB stick can be subdivided as any other HDD could: first gpart create, then newfs. So,
gpart create -s MBR /dev/usbstickthen
gpart add -t freebsd -s <size you want> /dev/usbstickand finally,
mount -t ufs /dev/usbstick /mount/point. If a USB stick might be used for an installer image, one slice could be 5120M and the remaining space is chosen by leaving off the size designation, such as
gpart add -t freebsd /dev/usbstick. To use the first partition of the usb stick for the image, use
dd if=<image> of=/dev/da0s1 bs=512M.
- Dolphin/Device Notifier caveat: It may allow a mount point within /media to be created, but it is possible that the ownership or permissions could be wrong. Best case is that /media/mountname is owned by you and wheel group.
chown username:wheel /media/mountname.
- Live media caveat: This method may not be compatible with booting the usb on any random system. In that situation, simply zero and then dd the image to the stick. Perhaps if the BSD boot selector is added it may work, but that has not yet been verified.
Of course the above is generic and some adjustments are needed.
