Testarea unui nou kernel folosind Grub

Exista doua alternative:

- cea simpla:

grub> help savedefault

savedefault: savedefault [--stage2=STAGE2_FILE] [--default=DEFAULT] [--once]
Save DEFAULT as the default boot entry in STAGE2_FILE. If '--once' is specified, the default is reset after the next reboot.

E destul de clar ce face, nu dau explicatii suplimentare (pacat ca in manual nu este documentata treaba asta cu 'once').

- cea complicata, manarind situatia cu 'default' si 'savedefault':

         default saved
         timeout 3

         title GNU/Linux
         root (hd0,0)
         kernel /boot/vmlinuz root=/dev/sda1 vga=ext
         initrd /boot/initrd
         savedefault

         title FreeBSD
         root (hd0,a)
         kernel /boot/loader
         default 0

Indiferent daca boot-eaza sau nu in FreeBSD, data viitoare va porni in Linux.
