Hi,
is the no way to get a menu
Arch kernel 1 Arch Kernel 2 Foo Kernel 1 Foo Kernel 2
when using syslinux?
Or even while booting another Linux requires chainloading, there's a feature to chose between all available kernels of another Linux by the "main" menu?
IIUC chainloading only could provide
Arch kernel 1 Arch Kernel 2 Foo
and just when selecting Foo I can chose between
Foo Kernel 1 Foo Kernel 2
and perhaps
Arch
so assuming I then decide to go back to the Arch menu, I need to chainload Arch from the chainloaded other Foo Linux?
No, you only need chainloading in special cases, for instance if syslinux can't boot from a filesystem containing Foo kernels, or windows. Let's assume that you have the following: * /dev/sda1 -- mounted at /boot when you boot your ArchLinux system * /dev/sdb1 -- the same for Foo * syslinux is installed on /dev/sda1 (it is bootable). What I usually do, is mkdir /dev/sda1/{arch,foo} and rsync kernels/initrds from /dev/sda1 to arch/ and from /dev/sdb1 to foo/. Then, modify syslinux.cfg so that entries like LINUX ../vmlinuz-linux become LINUX ../arch/vmlinuz-linux and similarly for INITRD. Finally, in your Arch's and Foo's fstabs, bind-mount arch/ and foo/ to respective /boot's (if desired of course, as you don't need to have /boot mounted). This way you get the menu that you mentioned first. You no longer need data in /dev/sdb1 and can free the partition. HTH, -- Leonid Isaev
