I am trying out Funtoo on a new machine. I've been through the installation process, as described in Funtoo Linux Installation . Specifically, the installation is done from within an existing Linux distro via chroot, though in a new empty SSD. All went fine up to the point of installing the bootloader which fails:

grub-install --no-floppy /dev/sda
source_dir doesn't exist. Please specify --target or --directory

The partitions created are:

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048         1026047   500.0 MiB   8300  Linux filesystem
   2         1026048         1091583   32.0 MiB    EF02  BIOS boot partition
   3         1091584       269527039   128.0 GiB   8200  Linux swap
   4       269527040       395356159   60.0 GiB    8300  Linux filesystem
   5       395356160       479242239   40.0 GiB    8300  Linux filesystem
   6       479242240       500118158   10.0 GiB    8300  Linux filesystem

and the /etc/fstab looks like

/dev/sda1               /boot           ext2            noatime 1 2
/dev/sda3               none            swap            sw              0 0
/dev/sda4               /               ext4            noatime         0 1
/dev/sda5               /osgeo          ext4            auto,rw,exec,user 0 2
/dev/sda6               /home           ext4            defaults,noatime 0 2
#/dev/cdrom             /mnt/cdrom      auto            noauto,ro       0 0

The /dev/sda1 partition is mounted as reported by mount

/dev/sda1 on /boot type ext2 (rw,relatime)

If it matters, the existing Linux distro has a similar GPT scheme, of course, in another disk than the target for Funtoo. Some info about it:

cat /proc/mounts | grep boot
/dev/sdb1 /boot ext4 rw,relatime,data=ordered 0 0
/dev/sdb2 /boot/efi vfat rw,relatime,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
/dev/sda1 /boot ext2 rw,noatime 0 0

What else is there to be done? Do I have to mount /dev/sda2 as well?

Thanks for any hints!

You have to mount both / and /boot and specify /boot as target, so the complete command shall be grub-install --no-floppy /dev/sda --target /boot, btw, why two drivers mounted in /boot? –  Braiam Jul 5 '13 at 22:07
Thanks @Braiam I answered below... nothing special, really :-/. The partitions in sdb are the ones of the current running Linux system. The entry mounting /dev/sda was actually inside /mnt/funtoo/boot. I did follow closely the installation guide. –  Nikos Alexandris Jul 5 '13 at 22:43
I can't explain why exactly it didn't work "out of the box". I guess it has to do with the fact of chroot-ing from another, running, Linux system. I'll wait a bit for comments/ideas if this is of interest. Otherwise, I will (vote to) close this question. –  Nikos Alexandris Jul 5 '13 at 22:46
@Braiam As for the two boot partitions, I am not exactly sure... it's openSUSE's guide which I followed (not that closely though, if I remember well). –  Nikos Alexandris Jul 5 '13 at 22:49

I just exited from chroot, unmounted all partitions, rebooted (the other Linux distro), and re-did the same stuff (following It simply worked!
