Comment 1 for bug 38171

I had a similar issue with the graphical installer, not sure if it is related. I attempted to use the "manually configure partitions" from the liveCD Dapper install (RC1). I removed two logical partitions (one 1004 MB swap and one 23 Gig /), then tried to create an 8 Gig /, 1200 MB swap, and the rest /home. The installer would try to keep a 1004 MB swap partition size, make the 8 Gig partition swap space also, and would put / and on the 15 Gig partition. I tried re-partitioning with the graphical installer a couple times but would have the same issue everytime. I then booted using a gparted liveCD to format the partitions, and then the dapper liveCD installer worked fine using those partitions.
