To answer your question why I found it necessary to change the filesystem, the answer is that I didn't. It was a slip of the mouse and I accidentally selected ext2 instead of ext3 or vice versa. (This would have been less likely, but still not impossible, to happen if the existing filesystem on the partition was already highlighted or pre- selected in the drop-down box, but it wasn't.)
Is it worth a pop-up warning dialog? Yes, I think causing a partition to be formatted by an indirect method (remember, I very intentionally had left the Format Partition checkbox UNCHECKED!), is worth a pop-up warning. I can assure you that if I hadn't noticed and caught the accidental error and if Ubuntu had gone ahead and reformatted my partition, I would have had some very nasty words to say about Ubuntu installers!!! -- manual partitioner automatically selects "format" when changing file system, without warning https://bugs.launchpad.net/bugs/262504 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
