YDL 2.2 install fails at transfering packages

[Gordon Neault]

You need a fair partition to do the install. I don't know exactly where 
the line is, but it's definitely between 1 and 2 GB somewhere.
If you create more than one Linux partition (ie /home, /var, etc plus root)
  you must make sure these partitions have enough space as well.
A major part of it is the temporary storage of packages after they are 
uncompressed but not yet installed.

Performa 5200 will not work with YDL.
