Details:
grub does not set variables consistently:
root="tftp"
prefix="(tftp,172.18.8.1)/grub"
cmdpath="(tftp,172.18.8.1)grub/i386-pc"
locale_dir="/grub/locale"
themes_dir="grub/themes"
this is without any configuration file. "themes_dir" seems only set if a
themes directory exists.
Resolving any of these it it depends on prefix what is seen:
cmdpath -> (tftp,172.18.8.1)/grub/i386-pc -> is not expanded
locale_dir -> (tftp,172.18.8.1)/grub/locale
themes_dir -> (tftp,172.18.8.1)/grub/grub/themes
Accessing "root" leads to "disk tftp not found"
as soon as "root" is set to "(tftp)" it will work as expected. But as a side
effect it sets "prefix" to "(tftp)".
Shouldn't grub set all Variables refering "root" and "prefix" the same way?
Aka:
root="(tftp,172.18.8.1)"
prefix="(tftp,172.18.8.1)/grub"
cmdpath="(tftp,172.18.8.1)/grub/i386-pc"
locale_dir="(tftp,172.18.8.1)/grub/locale"
themes_dir="(tftp,172.18.8.1)/grub/themes"
or if it is expected them to be relative to an absolute device:
root="(tftp,172.18.8.1)"
prefix="(tftp,172.18.8.1)grub"
cmdpath="(tftp,172.18.8.1)grub/i386-pc"
locale_dir="(tftp,172.18.8.1)grub/locale"
themes_dir="(tftp,172.18.8.1)grub/themes"
or completely relative paths:
root="(tftp,172.18.8.1)"
prefix="grub"
cmdpath="i386-pc"
locale_dir="locale"
themes_dir="themes"
or "root" depending on "net_default_server":
net_default_server="172.18.8.1"
root="(tftp)"
The way it is done now leads to a mess of different necessary setups if using
these variables any to make it more annoying to different behavior depending
on other variables.
