I was doing an experiment with the upgrade tool. I wanted to test if Comodo Anti-Virus would survive an upgrade from Precise to Trusty. CAV would not work with the new Trusty kernels so I did the procedure for fix to activate filters and it still would not work. I notice in Grub an instance:
Code:
ventrical@ventrical-MS-7798:~$ uname -a
Linux ventrical-MS-7798 3.5.0-54-generic #81~precise1-Ubuntu SMP Tue Jul 15 04:05:58 UTC 2014 i686 i686 i686 GNU/Linux
and so I booted from there and now CAV works better than before and lsb_release still tells me I am in trusty:
Code:
ventrical@ventrical-MS-7798:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
ventrical@ventrical-MS-7798:~$
so theoretically, by preserving the last kernel update from precise and appending it to the new upgrade it more or less effectively created a Precise (12.04) shell of sorts, preserving the config and kernel bindings for Comodo AV.
More amazing stuff I've learned about Ubuntu!
