Do both OSX AND YDL need to be in 8GB for old Macs?

[john gardiner]

Following on from assistance on asking about a terminating installer, 
have got as far as trying to reinstall YDL 3.0.1 into the first 8GB. 
The partition map looks like YDL root and swap all in first 7.5GB, next 
9Gb or so is /home, then the rest of the drive (another 17GB or so) is 
OSX. The OSX system still boots fine but still get YDL essentially 
completely installed, but it fails right at the end when 
checking/completing the install.

Surely OSX doesn't also need to be in the first 8GB (as putting 
OSX+extras AND a YDL workstation install all into the first 8Gb would 
be a bit of a cram)?

The fact that the OSX alone runs fine suggests it is Ok where it is. 
has anyone else successfully installed YDL plus OSX on a rev 1 G3 B&W 
wih OSX in a partition beyond the first 8GB?

Many thanks.
