Re: error in bootloader config while system init

[znavko@disroot.org]

I have another error with Grub bootloader here:

# guix system init /mnt/etc/config.scm /mnt 2>1
# cat 1 | nc termbin.com 999

error: '/gnu/store/9kvnp0vp24vplnwxd7svr8mlcbxa2f0l-grub-2.02/sbin/grub-install --no-floppy
--target=i386-pc --boot-directory /mnt/boot /dev/sdb' exited with status 1; output follows:

UNRELIABLE and their use is discouraged..

guix system: error: failed to install bootloader

# cat /mnt/etc/config.scm | nc termbin.com 999

Here it the bootloader section:
(operating-system (host-name "antelope") (timezone "Europe/Moscow") (locale "en_US.utf8")
(bootloader 
(bootloader-configuration 
(bootloader grub-bootloader) 
(target "/dev/sdb")))

(initrd-modules (append (list "sata_sis")
%base-initrd-modules))

(file-systems (cons 
(file-system 
(device "/dev/sdb1") 
(mount-point "/") 
(type "ext4")) 
%base-file-systems))
(swap-devices '("/dev/sdb2"))
...

# fdisk -l
...
Device Start End Sectors Size Type
/dev/sdb1 2048 104859647 104857600 50G Linux filesystem
/dev/sdb2 104859648 125045390 20185743 9.6G Linux swap



As I understood, guix needs another disk partition, one separate for grub.
I tried this but unsuccessfully:

# fdisk -l 

Device        Start       End  Sectors  Size Type
/dev/sdb1      2048  15626239 15624192  7.5G BIOS boot

/dev/sdb3  99610624 125045390 25434767 12.1G Linux swap
