On sda1, I have only kernel 3.5.0 installed (sabayon 10.64bit KDE..up to date)
on a USB stick, I only have kernel 3.4.0 installed (sabayon 8 KDE 64-bit)
Upon booting , I select the entry for the USB stick. This, however, always loads sda1 as root....with kernel 3.4 running , acording to uname-a:
- Code: Select all
sabayon@sabayon ~/Documents $ uname -a
Linux sabayon 3.4.0-sabayon #1 SMP Tue Jun 19 16:26:07 UTC 2012 x86_64 Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz GenuineIntel GNU/Linux
sabayon@sabayon ~/Documents $ eselect kernel list
Available kernel symlink targets:
[1] linux-3.5.0-sabayon *
Some items like network manager and sound do not work in this setup.
When I check the partition manager after booting via the usb stick entry in grub, it shows sda 1+2 mounted and sdb not
I used to be able to load the USB stick until I messed around with UUIDs, changing one of them , as sda1 previously matched the partition on the USB stick...and also changing the grub.cfg + fstab to match.
I could try changing it back but am trying to understand what is happening first and see if there is a different solution.

(The path to the USB stick partitions change to /dev/sdb1 + sdb2 when I boot via the usb entry in grub.)
Any idea what's happening here?
