Hi, aparently this happens on certain partition configurations, but current snapshots (tried many different days and dual, net, i686, x86_64) have a problem where partitions are not correctly detected. They appear repeateadly, and you cannot set mount points.
There are at least two bug reports about this:
After getting some hints from the reports. You workaround it by editing at the prompt and then going back to the install:
Edit /tmp/aif/aif-blockdata to something similar:
/dev/sda2 raw no_label swap;yes;no_mountpoint;target;no_opts;no_label;no_params
/dev/sda3 raw no_label ext4;yes;/;target;no_opts;no_label;no_params'
you can run fdisk -l before to be sure of your partitions (warning this sample will format partitions)
Hope it helps anyone!
I was banging my head against the wall till I read this. Thanks!
