17 I made the switch a good while back.  Even for me, it has been fairly
18 easy.  I don't recall it ever breaking or giving me trouble.  When I
19 build a new kernel and get the init thingy in /boot, I run this command
20 to update grub.
21
22 grub2-mkconfig -o /boot/grub2/grub.cfg
23
24 I put it in a little script and just run the script, so I don't have to
25 remember the thing.  ;-)  The only thing I recall it being picky on, the
26 names of the kernel and the init thingy.  If they don't match correctly,
27 it won't match them up when you run the above.  A little sample of my
28 naming that works.

47 To your real desire, I don't think there is a minimal grub2 install. 
48 While bigger than the old Grub, it isn't to bad, given the size of
49 drives nowadays. 
50
51 root@fireball / # equery s grub
52  * sys-boot/grub-2.02-r1
53          Total files : 1207
54          Total size  : 50.85 MiB
55 root@fireball / #
56
57 If the old grub isn't being maintained anymore, from what I've read it
58 isn't, you will have to switch at some point.  If grub2 works for me, it
59 should work great for you.  I'm pretty good at finding problems. lol
