I sort of figured that if there was a major change, we would see some sort of message about needing to reinstall before rebooting. Thanks much. Dale :-) :-)

I don't think I've ever updated what's in the mbr. It doesn't really matter in that it just hands over to the real linux and root. I think it would be rather hard to compromise, and anyway if anything has got so far as to tamper with your boot, I think the game is over anyway. Most changes of any consequence will be to the user-space code anyway, not the actual boot stuff. Cheers, Wol

I used equery f grub to see what grub installed where but it showed nothing at all for /boot. I figure grub-install puts all the needed files in /boot but I wasn't sure how to get it to list where it put them. The file isn't a script so I can't just peek into the file and see what it does. While I'm at it. When the grub package upgrades, should I reinstall with grub-install to update what is on the drive or is it safe to just leave it as is? I seem to recall a upgrade to grub a while back. It just dawned on me that while the package is updated, what is installed on the hard drive boot part with grub-install is still the original from ages ago when I first built this rig. Thoughts?? Dale :-) :-)

Yes, but to be on the safe side, rename it rather than removing it. GRUB will look in either /boot/grub or /boot/grub2, from your setup it looks like it goes for grub2 first. -- Neil Bothwick All right, set phasers to deep fat fry! pgpE1SQqce54D.pgp Description: OpenPGP digital signature
[gentoo-user] /boot/grub and grub2 directories
Howdy, I was cleaning out my /boot directory. It's on its own partition and I remove outdated kernels and configs etc every once in a while. I was noticing that I have two grub directories. Based on time stamps, I think I can delete the plain grub directory and I'm pretty much certain grub2 is the current and active grub directory. Is it safe to remove the old grub directory? Nothing in it has been touched that the time stamps show in a long while. The grub2 directory was when I did my last kernel update. I just want to be certain before I remove the directory. More info below. ls -al /boot/ drwxr-xr-x 6 root root 17408 Jun 18 2019 grub drwxr-xr-x 6 root root 1024 Nov 30 10:55 grub2 By the way, I had the old grub installed on here ages ago. Can't recall when I switched to the new, much larger, grub2. Thanks. Dale :-) :-)
