(i know this is not "officially supported" but i'd still like to do it this way.)
i use LE in a multiboot-config with linux and grub on an x86_64-PC. Ususally i use one BTRFS-filesystem and each (Linux-)OS (or rather its rootfs) resides in its own subvolume there; one install maintains grub but its config (grub.cfg) is simple (just a couple of lines per distro) and can easily be adapted. Homedirs, mediafiles etc ususally reside on a different btrfs-disk in their own subvols.
i'd like to have one subvol for LE which contains both KERNEL and SYSTEM and LE_DATA (/storage) in its own subvol.
the following config works:
KERNEL is inside /boot of one distro, SYSTEM is in btrfs-subvol in extra-partition (sda2, btrfs, labelled LE_DATA) and this is also mounted as storage. the media-dirs on the other disk are easily accessible inn /var/media/somwhere....)
grub.cfg:
# 20210824 medi + LE
set timeout=5
menuentry ' :: KODI on GENTOO :: ' {
set root=(hd0,gpt1)
linux /GENROOT/boot/5.13.12 root=/dev/sda1 rootflags=subvol=GENROOT rootfstype=btrfs net.ifnames=0
}
menuentry 'LibreELEC' {
linux (hd0,gpt1)/GENROOT/boot/KERNEL boot=/dev/sda2 disk=/dev/sda2 rootfstype=btrfs
}sda2 ist labelled LE_DATA and its default-subvol is also LE_DATA
i'd like to keep KERNEL and SYSTEM in their own subvol.
configuring grub to boot
linux (hd0,gpt1)/LE/KERNEL (...)is probably no problem but i don't know how to configure the remaining parts.
considering the pxeboot/NFS-documentation i think it's quite flexible but i do not know the parameters/syntax.
is there an doc or can anybody tell me sth. about the APPEND=-statement ?
THX for your input!
