Hello, I'm trying to get the hostname in `grub.cfg` to point then to different rootnfs, or network live images.
From the manual page: https://www.gnu.org/software/grub/manual/grub/grub.html I've noticed the existence of `net_<interface>_hostname` but this requires to know the `<interface>` name in advance and this is platform dependent (as the documentation says). Since these systems have only one network connection I thought about using `net_default_interface` to ignore the specific name. Here problems strarts because neasting variables seems not working and doing: `${net_${net_default_interface}_hostname}` However, in the documentation variables like `net_default_ip` are described as the result of ‘net_${net_default_interface}_ip’. Am I doing something wrong? Do you have any suggestion? Thanks
