I can confirm that: right after I posted, I rebooted and all hell broke
loose. I just got booted up again (I'd already removed gcc-5) using grub2.
I was genuinely annoyed with grub2 due to its update and massive config
files, so I never upgraded to it. I usually had multiple kernel versions
and grub2 helpfully labeled them all "Linux" so I couldn't tell them apart.
I figured out you can still write your own grub2 files, and it wasn't
that difficult, other than its numbering is different now (no base-0
partitions... argh.)
Below is an example of a simple grub.cfg that starts two separate
kernels (I use a different kernel/partition for MythTV) and a
chainloader for Windows 7. It took a few iterations for me to get
everything to boot.
My partitions are as follows:
/dev/sda1: Windows tiny partition, the bootable one
/dev/sda2: Windows 7
/dev/sda3: /boot
As you can see, there's no base-0 counted partitions in the config, that
messed me up more than once.
I also used PARTUUID for the root= parameter, you can get this by using
`blkid /dev/sdaX`. Also, don't encapsulate your PARTUUID in quotes, that
didn't work for me. I simply had (as an example)
root=PARTUUID=abcdef33-01 and it boots fine.
It was simple enough to convert (and grub-2.02 actually compiles fine
with gcc-6 and the new profile) and figured others were probably like me
and avoiding the grub2 config mess.
At least now I know how to configure grub2 manually and simply, so I
won't avoid it any more.
