Brad, [snip from below] it *seems* like you should be okay unless you try to back up two instances simultaneously (or perform other simultaneous write operations to /dev/ubd0) [/snip]
I ran simultaneous full back ups and timed it so that I did both, backing up the same file on both at the same time and backing up different files at the same time. When I rebooted both UML routers they came up fine. I was unable to find any problems. [snip from below] It also seems like you could overwrite a package backup from one instance with a later backup from a second instance [/snip] This I have also tested and it did not cause a problem. I just did a simple name change on each router and then backed one up and then the other. I then rebooted both and they came up with the new names just as I had set them. Let me know if you think of anything else that might cause a problem and I will go ahead and test it.

Since Bering runs from a ram disk and the boot file system is typically not mounted except during package backups, it *seems* like you should be okay unless you try to back up two instances simulaneously (or perform other simultaneous write operations to /dev/ubd0). It also seems like you could overwrite a package backup from one instance with a later backup from a second instance (which may be desirable, depending on what you are trying to accomplish). All that is untested speculation though. > I backed up all my files in case something went wrong. > I booted up two Bering UML file systems and made some changes. > Saved changes. > Backed up /etc. > Rebooted Bering UML file systems. > Checked changes. > Everything seems to be working fine.
