Hello. ;) I am attempting to format my own custom bootable USB stick on
FreeBSD 8.3 and ran into some issues and questions. My USB stick is at
da0, and here's the sequence of what I am trying to do:
# gpart destroy -F da0
da0 destroyed
# gpart create -s MBR da0
da0 created
# gpart add -s32m -t \!14 da0
da0s1 added
# gpart set -a active -i 1 da0
active set on da0s1
# gpart add -t freebsd da0
da0s2 added
# gpart show da0s2
=> 0 15567804 da0s2 BSD (7.4G)
0 16 2 freebsd-ufs (8.0k)
16 15567788 1 freebsd-ufs (7.4G)
Now I want to label the partition da0s2a. From the documentation in the
man pages, I seem to be being told that
# gpart modify -l foo -i 1 da0s2a
will not work, and it doesn't:
gpart: Invalid argument
So let's try newfs:
# newfs -L foo /dev/da0s2a
...
# gpart show -l da0s2
=> 0 15567804 da0s2 BSD (7.4G)
0 16 2 (null) (8.0k)
16 15567788 1 (null) (7.4G)
and still the labels do not show up. I really do want to be able to
mount /dev/ufs/foo as the root device, but as I understand things if
gpart doesn't show the label then the glabel subsystem won't set up the
proper device file.
What gives here? Am I missing something important?
Thanks in advance.
