I read that Kali will now be a rolling release which means it will be upgrading packages frequently. This means the distro could break more than Kali 1.0 would now with the more frequent updates.
Is what i'm saying a possibility? it may not be like the Arch distro, but if there's chances for more frequent problems to it being a rolling distro then we should make frequent backups.
I'm personally waiting until moving onto Kali 2.0 until they sort through the problems with new things which is bound to happen it being new.
