Custom partitioning using standard partitioning using netinstall.

Want to reuse occupied ext4 partitions as install target.

Installer checked media before install.

Discussed at 2013-08-28 blocker review meeting [1]. This is accepted as an Alpha blocker, because it violates the following F20 alpha release criterion: "The installer must be able to complete an installation to a single disk using automatic partitioning." [2]

Apologies to caf.  My ill cat wearing a soft collar plunked herself down on my mouse and inadvertently clicked on the unsubscribe link he had included in a email to the test mailing list.  I hope I can add him back from the Cc: list.

I've tried to install this TC2 via HTTP several times. It errored early every time. This time was a second error at the same earliest point, without having clicked anything on the "spoke" screen, while waiting on all spokes except partitioning to reach ready state. Last click was on the beta software ackknowledgement.

If you haven't downloaded TC3 yet, don't waste your time.  It still has anaconda 20.9.1.  The fix for this problem is in 20.10.1.  I guess communication just got crossed.  The new version is on koji, in fact there is a 20.10.2 out there.  I might try downloading it and rebuilding the iso with the new version.  Or I might just wait for it to get fixed.

Finally this did not happen with TC5.

--- Additional comment from  on 2013-09-09 09:21:35 EDT ---

No issues with TC5 on this across multiple installation attempts. Everything proceeds as normal.

--- Additional comment from stan on 2013-09-09 13:09:30 EDT ---

TC5 does not get this error anymore.  Looks like anaconda 20-11.1 fixed it as it said it would.  Unfortunately, while this bug seems to be fixed, TC5 failed every time with bug BZ 1004846.

Verified on anaconda-19.31.51-1.el7. I was able to install system with btrfs on one device via custom partition screen.
