While installing on my notebook (dell inspiron 7500) and workstation (scsi based hd/cdrom), i ran into a behavioural bug.. It prompts for CD2 to be inserted, i do so, wait a few seconds, and press OK .. it prompts that it couldnt find the CD. When pressing OK again for the second time, it does find the CD.. (yes i did wait the spinup/detect time for the cdrom, so to be sure it could find it)
That you for the report we will address this in our next release.
If the new mount fails, we wait 3 seconds and try again before reporting an error now. Hopefully, this will fix your problems.
this fix (although not verified directly) has passed regression tests ... please reopen if still an issue in future releases ... thanks for your report!
