Hello everyone!
Can someone help me with this? I recently installed Guix on a btrfs-volume but
forgot to put it onto a subvolume. I tried to remedy that mistake by creating a
subvolume \@, copying the data from the main volume on it and putting the
following into my system config:
(file-systems
(list
(file-system
(device (file-system-label "root"))
(mount-point "/")
(type "btrfs")
(options "subvol=@"))))
when I do this, I can reconfigure
when I do this I can reconfigure without problems and it produces a grub.cfg
with the following main entry
menuentry "GNU with Linux 6.15.5" {
search --label --set root
linux /gnu/store/mc78fnlglamkv0bdq927hmdql30h9qxk-linux-6.15.5/bzImage
root=root gnu.system=/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system
gnu.load=/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system/boot
modprobe.blacklist=usbmouse,usbkbd quiet
initrd /gnu/store/p4apajqwkw8898fwjjb34h9gg7lp00w5-combined-initrd/initrd.img
}
but when I boot I get a message that
/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system/boot is not found and am
thrown into a Guile shell. This is even though
/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system/boot exists. I'm guessing
this is because of this (from the manual):
"Some bootloaders, for example GRUB, only mount a Btrfs partition at
its top level during the early boot, and rely on their configuration to
refer to the correct subvolume path within that top level… it is therefore
necessary to extract the subvolume name on which ‘/gnu/store’ lives"
But I'm not sure how or what to do about it. I tried to copy
/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system to /@/store/ and replace the
reference to /gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system and
/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system/boot with
/@/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system/ and
/@/gnu/store/672a1xlckzpvsms2xbkdwn28297vj6w9-system/boot but I still got the
same error. So I'm not sure about what to do next. What do I have to do to get
my Guix system onto a btrfs subvolume?
