In Terminal, if you type:
cd /boot
du -h
... it shows the /boot
directory usage.
Mine only shows:
du -h
5.5K ./grub
9.5K ./efi/grub
10K ./efi
128M .
Is that everything that's supposed to be in there for a SecureBoot setup on a UEFI system?
I'm seeing others online post stuff like:
du -h
3.4M ./grub/x86_64-efi
2.3M ./grub/fonts
8.0M ./grub
3.4M ./efi/grub/x86_64-efi
2.3M ./efi/grub/fonts
8.0M ./efi/grub
21M ./efi/EFI/ubuntu/fw
25M ./efi/EFI/ubuntu
3.7M ./efi/EFI/BOOT
... and while I've not purposefully deleted anything under /boot
, I wonder if some things did somehow get deleted.
I've been working through the dpkg list of installed packages and removing stuff I know I won't use (and which won't bork my installation due to dependencies when it's removed)... so I've got a fully-functioning Zorin OS taking only 5.15 GB of hard drive space. I'm wondering if I somehow scalpeled a bit too much out.
If the dependencies made any semblance of sense, I could cut out a few additional hundreds of MB. For instance, I found that when attempting to remove one particular font, the dependency tree also caused apt
to want to remove BlueTooth functionality.
