Yes, PCNetSpec, I think I get it.
With the exception of some bugs that will most likely be ironed out in either Lubuntu or Peppemint OSes within the next several months. The kernel, which is the same in both Lubuntu and Peppermint, will be supported/patched/updated/upgraded for security for the next five years, or until April 2019.
Peripheral issues such as pacmanfm (Isn't that our file folder?) could potentially manifest security issues, and these possible, but unlikely, security issues may well not be addressed if they were ever to occur at all after April 2017 for Lubuntu, or after Peppermint 6's release. But the chances of these types of issues occurring after these dates is very, very, remote because most, if not all of these bugs, will most likely have been discovered and ironed out by then.
So what we're saying here is that both Lubuntu and Peppermint with be theoretically 100% secure for some time. For Lubuntu until April 2017, and for Peppermint 5 until Peppermint 6's release. Then after April 2017, the kernel of Lubuntu with only receive security support until April 2019, and the same for Peppermint 5 after Peppermint 6's release -- only security support for the kernel until 2019. And this is 98% of what updating and upgrading is all about anyway when it comes to matters of importance, namely that of security. So with the exception of some unforeseen event, both OSes, Lubuntu and Peppermint, will be essentially secure until 2019. And most other, if not all, peripheral bugs including security bugs of LXDE specific issues will have been more likely resolved by then too.
How's that? Am I still understanding how this process works?
Thank you,
