Semi newbie question

[Olaf Olson]

Strange how it happens that two people can be thinking and/or 
questioning the same thing at the same time. Maybe not, if you consider 
our numbers, but...

I was just trying to move some stuff from my YDL 3.0.1 installation on a 
G3 B&W, to the Mac OSX partition on the drive. pdisk reports:

[root@PlanB-YDL proc]# pdisk -l

Partition map (with 512 byte blocks) on '/dev/hda'

That suggests that sda9 is the drive I want to write to.

I followed your instructions, although I am more of an anarchist, and 
stuck the mountpoint at the / level, rather than /mnt. Anyway, it 
mounted, with no errors. This is all I see, when I list the directory:

[root@PlanB-YDL mol]# ls -al

-rwxr--r--    1 root     root            0 Mar 26 21:21 System


Just for grins, I read the ReadMe file (It's those friendly capital 
letters) and found this:

AHA! said I, or something to that effect. Although I recall carefully 
reading the instructions for installing YDL 3.0, that said to partition 
with an hfs format, not hfs+, apparently I used the Extended format.

Now, the tricky part. If I change fstab, to specify hfs+, I get a "not 
supported on this kernel" message.

FINALLY - here is the question. How do I make it possible to read/write 
hfs+, or what is the correct word to use to describe Mac OS Extended format?

Thanks

Olaf
