Today I tried this out, making a /boot/ partition on the harddisk and changing /etc/fstab accordingly. It is workable while the card remains in the expresscard-cardreader, but not workable, when it is inserted in the internal mmcblk-cardreader. Running update-grub on the stable system on the harddisk is not sufficient to make things work: > andrew@jessie:~$ ls -la /dev/disk/by-uuid/ > total 0 > drwxr-xr-x 2 root root 140 Feb 25 11:38 . > drwxr-xr-x 5 root root 100 Feb 25 11:33 .. > lrwxrwxrwx 1 root root 10 Feb 25 11:33 0dde64dc-8274-4266-a810-f9aee59153e8 > -> ../../sdb5 lrwxrwxrwx 1 root root 10 Feb 25 11:38 > 200716dc-4394-44af-94d4-304c05e4d84b -> ../../sda5 lrwxrwxrwx 1 root root 10 > Feb 25 > 11:38 51909eab-ae25-46af-841d-62fbbd1dd7a2 -> ../../sda3 lrwxrwxrwx 1 root > root 10 Feb > 25 11:33 5e1b75fa-a3cc-4d0a-a535-6ef327488c44 -> ../../sdb1 lrwxrwxrwx 1 root > root 10 > Feb 25 11:38 c650ce84-00cc-45e6-86bb-c792e524028c -> ../../sda1 > andrew@jessie:~$ sudo > gedit /etc/fstab > > (gedit:1942): Gtk-WARNING **: Calling Inhibit failed: > GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name > org.gnome.SessionManager was not provided by any .service files > > (gedit:1942): Gtk-WARNING **: Calling Inhibit failed: > GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name > org.gnome.SessionManager was not provided by any .service files > > (gedit:1942): Gtk-WARNING **: Calling Inhibit failed: > GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name > org.gnome.SessionManager was not provided by any .service files > > ** (gedit:1942): WARNING **: Set document metadata failed: Setting attribute > metadata::gedit-spell-language not supported > > ** (gedit:1942): WARNING **: Set document metadata failed: Setting attribute > metadata::gedit-encoding not supported andrew@jessie:~$ sudo mount /dev/sda3/ > /boot/ > mount: special device /dev/sda3/ does not exist (a path prefix is not a > directory) > andrew@jessie:~$ sudo mount /dev/sda3 /boot/ > andrew@jessie:~$ sudo update-grub > Generating grub configuration file ... > Found background image: /usr/share/images/desktop-base/desktop-grub.png > Found linux image: /boot/vmlinuz-3.16.0-4-686-pae > Found initrd image: /boot/initrd.img-3.16.0-4-686-pae > Found linux image: /boot/vmlinuz-3.16-3-686-pae > Found initrd image: /boot/initrd.img-3.16-3-686-pae > Found Debian GNU/Linux (7.8) on /dev/sda1 > done > fstab looks like this: > # /etc/fstab: static file system information. > # > # Use 'blkid' to print the universally unique identifier for a > # device; this may be used with UUID= as a more robust way to name devices > # that works even if disks are added and removed.

Maybe it is only a matter of chrooting prior to doing update-grub, possible something like this does the trick: > 3) Setup a working grub.cfg > Since it is recommended to not edit grub.cfg directly in Grub2 I just added > the > following entry to /etc/grub.d/40_custom > > menuentry "Arch (on /dev/mmcblk0p1) custom" { > set root='(hd0,5)' > linux /boot/vmlinuz26-custom root=/dev/mmcblk0p1 > initrd /boot/kernel26-custom.img > } It should work anyway, when installing newly. I remember, I had similar problems, when trying to move an exiting system onto an md-raid, most probably I am not familiar enough with grub2 yet. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlTt420ACgkQ5+rBHyUt5wvJnACdEumqQvma8wvGlmc9ETMvF3zo JOMAnR6i8lAylxOIQSDgdOjXh92w6oWQ =1p16 -----END PGP SIGNATURE-----
