info on multiboot f23 and c7

[Gianluca Cecchi]

Hello,
I have a nuc6i5 where I have 2 SSD disks.
The M.2 one (250Gb) is seen as sdb, while the sata one (500Gb) as sda.
Initially I have installed f23 on the one seen as /dev/sdb and I presume
the boot loader has been installed on it, correct? How to check?

In a second moment I installed CentOS 7.2 specifying its new partitions
still on the second disk (I plan to use the first as data disk only).

With my surprise CentOS 7 made all in a fantastic way, in the sense that
during the partitioning part it recognized the fedora 23 partitions and its
lvm parts and without asking anything (actually there was no option to
manage grub configuration at all...) it configured its (I think) grub2 so
that the menu contains also the fedora 23 lines (normal one and one labeled
as "Advanced options for Fedora 23...") and they work as expected

So far so good, it went better than I imagined...

Now I have a kernel update proposal for Fedora 23 and I have not applied it
because I don'tknow if it can break anything or not (eg replace grub
configuration or so on...)
ANd the same doubt would be when a CentOS 7 new kernel will be available.

For both the OSes I configured a (different) /boot partition, if this can
be of any importance.

BTW: lastly I would like in the near future to install also the free
version of ESXi to make some tests with it and with oVirt (planned to be
installed on the CentOS 7 OS part), while the Fedora 23 part would be to be
used as a pure desktop one (that already is in place and works like a
charm!)


Thanks in advance for any tip.
