I bet it's related to BootLoaderSpec. If you look at the

  ### BEGIN /etc/grub.d/10_linux ###

section of grub.cfg you will see:

  # The blscfg command parses the BootLoaderSpec files stored in
  # /boot/loader/entries and populates the boot menu. Please refer to 
the Boot

  # Loader Specification documentation for the files format:
  # https://systemd.io/BOOT_LOADER_SPECIFICATION/.



Ah - that sounds promising! - I will have a look at that - I would like 
a better understanding of how grub2 operates before I start messing 
around with adding entries to grub.cfg manually . .


Thanks!

Phil.

Installed Fedora 38 (sway) / grub2 on a new HD - boots OK but does not have a menuentry item in grub.cfg ?

2023-04-21 Thread Philip Rhoades via users 

People,

My Fedora WS has 4 drive bays and I access old boot and other HDs in 
bays 2-4.  I just did a clean install of Fedora Sway to /dev/sda - 
everything is fine and the system boots OK but I am confused:


- cat /etc/os-release

NAME="Fedora Linux"
VERSION="38 (Sway)"
.
PRETTY_NAME="Fedora Linux 38 (Sway)"
ANSI_COLOR="0;38;2;60;110;180"
.
VARIANT="Sway"
VARIANT_ID=sway

- The install picked up old Fedora boot setups which show up in 
/boot/grub2/grub.conf like this:


menuentry 'Fedora Linux 37 (KDE Plasma) (on /dev/sde3)' --class 
gnu-linux --class gnu --class os $menuentry_id_option 
'osprober-gnulinux-/boot/vmlinuz-6.0.7-301.fc37.x86_64--f6f43412-e6ed-4dff-808b-fe013691c3b6' 
{


- but why is there is not a line like this in /boot/grub2/grub.conf for 
Fedora 38 Sway?


I can see that the appropriate other Sway files are in the /boot tree so 
I am guessing that grub2 somehow knows the proper, default boot image - 
even though the default does not have a menuentry in grub.cfg?


A pointer to a link for info would be great . .

Thanks!

Phil.
