  • [gentoo-user] /boot/grub and grub2 directories

    From Dale@21:1/5 to All on Sat Dec 4 06:30:01 2021
    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    remove outdated kernels and configs etc every once in a while.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

    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.

    All right, set phasers to deep fat fry!

    That's a good idea.  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??

    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

    That info is very helpful.  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.
