Gentoo notebook: Aggiornamento in difficoltà

[Zievatron]

Ora si avvia?

Ma perchè mai ora dovrebbe avviarsi?
Ho già rifatto la prova più volte. Il grub.cfg è sempre quello e non si avvia.

[conoscenza]

sicuro che ora, il grub di salix e di gentoo, siano quelli postati qualche post fa?

Dai ripostami il tutto: i due grub, fdisk -l e blkid.

Bene. Anche qui come l'altro pc bypassi il grub di gentoo: non vedo nessun chainloader!

Sostituisce le righe:

menuentry "Gentoo Linux 3.2.12 (on /dev/sda6)" --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd0,msdos6)'
search --no-floppy --fs-uuid --set=root 99d78743-8b92-4db6-81cf-acb6239ceb71
linux /boot/kernel-3.2.12-gentoo root=/dev/sda6
}

con:

menuentry "Gentoo Linux 3.2.12 (on /dev/sda6)" --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd0,msdos6)'
search --no-floppy --fs-uuid --set=root 3f6da8d8-d003-4eb8-b429-cffeff309ba7
linux /boot/kernel-3.2.12-gentoo root=/dev/sda6
}

In realtà l'unica sostituizione sarebbe lo uuid del disco (grassettato).

Non capisco perchè te lo sbaglia sempre. Mi informerò a riguardo.

Se non dovesse andare postami:
ls -lR /boot/
di Gentoo.

e prova a sostituire le righe appena modificate nel grub di salix con:

menuentry "Gentoo Linux 3.2.12 (on /dev/sda6)" --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd0,msdos5)'
search --no-floppy --fs-uuid --set=root 3f6da8d8-d003-4eb8-b429-cffeff309ba7
linux /boot/kernel-3.2.12-gentoo root=/dev/sda6
}

ho messo:
set root='(hd0,msdos5)'
al posto di
set root='(hd0,msdos6)'

[Zievatron]

Ho modificato l'uuid.
Questa volta è partito, ma non è arrivato.
Si è fermato con una serie di righe di testo bianco tra le quali si leggeva di un kernel panic, perchè non poteva montare root.
Suppongo ci sia un file che riporta l'evento.
Se puoi dirmi dove guardare, vedo di raccattarlo e postarlo.

in chroot da salix, mi fai vedere:
ls -R /var/log/

in più mi posti:
eselect kernel list
ls -lR /boot/

Ora nel grub di salix hai:

menuentry "Gentoo Linux 3.2.12 (on /dev/sda6)" --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd0,msdos6)'
search --no-floppy --fs-uuid --set=root 3f6da8d8-d003-4eb8-b429-cffeff309ba7
linux /boot/kernel-3.2.12-gentoo root=/dev/sda6

Gisuto?

Aggiungici all'ultima riga "ro" trasformandola in:

linux /boot/kernel-3.2.12-gentoo root=/dev/sda6 ro

[Zievatron]

Fatto e riprovatoad avviare Gentoo.
Nessuna differenza.

[conoscenza]

nei /var/log/ non vedo boot.log, controlla che magari sia in /var/.

Se non lo è, ricopiamo il messaggio esatto che ti esce...
