Hello,
If you want to use the free space of 'g' you will have to delete it and
collapse all the partitions near 'd'. But is *dangerous*, and in fact
there are *no* tools (I searched and it is often said) to resize
filesystems (even if you resize the partition, the filesystem thinks
the space is still assigned to it, I think). The only think I believe is
possible (with raw tools: 'dd') is moving partitions, but if you
are moving less space than the size of the partition itself, it is only
possible to do it backwards, and the copied bytes will be overritten
(after copied) so if the process is interrupted you will lose all the
data (half in the destination, the rest in the original place, and one
immediatly following the other).
I found a (possible) better way to do this:
1) Revert the changes with the partitions 'd' and 'g' (back-up, delete,
create only 'd', restore).
2) Save the data in 'f' ('/home') to somewhere (like '/usr').
2) Delete 'f' ('/home') and create it with less space (like 10 GB, or
less, if you do not need much space there).
3) Then the BSD label entry 'c' should have less size.
4) Use 'fdisk' to resize the slice. It should be equal to the size of
partition 'c' (that is not a real partition, but the size sum of all
of them). Then the slice must not cover the entire disk, and you will
be able to create a 'msdosfs' slice after it (in the unallocated space).
I never tried this and I do not know if it is possible, so I *recommend*
you to back up your data.
Good Luck!
Best Regards,
Ale
