Ah :-(
¿Is that a bug I should report in bugzilla?
That's what I'm trying to find out.
Ah, ok, then just tell me when you have something else I could test.
And the missing "/sbin/mount.xfs"? What is that?
Normal, mount first checks if there is a special mount program for a filesystem.
I see.
I also have a concoction of zisofs compressed and xfs encripted filesystems, but that one is complex to test (it worked last time I tried some months back).
I don't understand what you mean. xfs is not an encryption algorithm it's a filesystem just as zisofs is.
Ok. I'll explain. - First I generate a zisofs compressed dvd image, using mkzftree (1) and "mkisofs -Z", which I name "zisofs.iso". - Create an xfs image of an encrypted filesystem (losetup, twofish, etc), in file '/Disco40/crypta.xfs.f' - I mount the xfs image, and copy on the resulting filesystem the iso9660/zisofs dvd image created earlier (zisofs.iso). - I umount the xfs image, and burn it to a dvd. The resulting dvd is both compressed and encrypted, and I mount it thus; in /etc/fstab I have: /Disco40/crypta.xfs.f /mnt/crypta.x9.dvdbck xfs loop,noauto,user,encryption=twofishSL92 0 0 #¡Encadenado! /mnt/crypta.x9.dvdbck/zisofs.iso /mnt/crypta.x9z.dvdbck auto loop,ro,noauto,user,exec 0 0 The above are the lines for the dvd creation step. For reading the dvd back, I lost the entries, but they should be: /dev/dvd /mnt/dvd.crypta.x9 auto ro,noauto,user,loop,encryption=twofishSL92 0 0 /mnt/dvd.crypta.x9/zisofs.iso /mnt/dvd.crypta.x9z auto loop,ro,noauto,user,exec 0 0 First, I do "mount /mnt/crypta.x9.dvdbck", the encrypted xfs image. Next, I loop mount the compressed image on it, using "mount /mnt/crypta.x9z.dvdbck". Not too weird, I hope ;-) (I use twofishSL92 inadvertently, as explained at the start of the thread)
I have no idea how to mount plain dvds using the device map thing, which
The device mapper is of no use there. You can just mount the device directly.
I know. I just mean that perhaps it is possible to test that way if mount is capable of mounting a plain dvd via this remaper thing, or if it only fails when it is encrypted. But maybe that's not an issue, I really don't know. You are the expert, so whatever you say :-) - -- Cheers, Carlos E.
