There is a boot parameter called "docache" that supposedly would copy the CD contents to RAM, and then let the user umount and eject the CD. I've tried to use it, but it did not work. Tried with 2008.0 beta 2 amd64 live-cd, in a notebook with 3GB or RAM. Reproducible: Always Steps to Reproduce: 1. Add "docache" as boot parameter. 2. Try to umount and eject the CD-ROM. Actual Results: You can't umount nor eject the CD. Expected Results: The CD contents should have been copied to RAM, so we would be able to umount and eject the CD.
Forgot to mention... I've reported it here: http://forums.gentoo.org/viewtopic-p-5122604.html#5122604
Care to provide us with some information like how it did not work? What errors did you get?
If you mean boot error messages, I probably have missed them. Care to tell me where they are logged? If you mean umount error messages, then that was because /mnt/livecd (or something like that) was still mounted. And, of course, it was still being used by the live system. Please tell me what you need, then later I gather this info for you.
I can confirm that for livedvd-i686-installer-2008.0_beta2.iso the "docache" option appears to work and do the actual caching during boot but does not allow umount /mnt/cdrom after booting which implies that the disc cannot be removed. People often use the docache option to allow them to swap discs after boot, previous releases allowed this and it works as normal on install-x86-minimal-2008.0_beta2.iso. Speculatively this appears to be an issue with graphical 2008.0 beta2 live cd/dvds keeping /mnt/cdrom busy after boot.
Did you stop spind first?
I've also noticed that if you use the docache feature it errors on unmounting '/' as its busy when shutting down :-( I see this error: * Remounting remainint filesystems read only ... umount: /: device is busy umount: /: device is busy umount: /: device is busy Give root password for maintenance (or type Control-D to continue): If you wait for a bit it does automatically shut down without having to do Control-D and without using docache the system powers off without an error!
Created attachment 173582 [details] Fix the unmount errors when using docache This patch fixes the unmount errors that I've been getting when using the docache option and stops the password for maintenance prompt resulting in a clean poweroff.
Don't send that to us. That's a baselayout thing.
yep, I now realise that one as it took me a while to figure out where the error message was coming from ;-) I will create a new bug for baselayout :-)
Did you do so?
No info in over 2 years and no reply to Raúl's request.
