I've written up a draft of an F13 filesystem rollback feature using
Btrfs snapshots that are automatically created by yum:
It'd be great to get feedback on whether this is the right idea, and
how exactly the UI interaction should work, before submitting this
So this will confuse things a lot if the user doesn't have only rpm
stuff on one partition, and everything else on another. This is
potentially a major risk. How would that be handled?
As the URL notes under "Detailed Description," that is not handled at
all. It wraps all file I/O, yum or not, into the snapshot.
A bloody awful solution, especially when you consider that btrfs'
maintainer Chris Mason is adding support for real userland transactions
(via some additional ioctls).
