Devi creare l'utente.

#adduser tuonome

Mi pare

Ok sorry ho risolto!  :sorriso: Prima installazione di arch... non credevo fosse così tosto..... :ysy:
Il problema è che dovevo entrare prima da root!

Nel processo di installazione di arch prima ti trovi a fare l'installazione base, poi al primo avvio senza cd ti trovi col solo account di root.

A quel punto devi creare un utente, aggiungerlo ad un gruppo che abbia i vari permessi spiegati nella wiki.

Poi installi il sistema grafico e tutto il resto.

Wiki è molto ampia e non è che c'è scritto tutto per filo e per segno, inoltre ho incontrato alcuni problemi che lì non vengono neanche menzionati, se a questo aggiungi il fatto che è la mia prima installazione di arch, è chiaro che posso fare delle cazzate, no?

Di nulla, figurati. Un consiglio solo: se puoi guarda sempre la wiki inglese. Quella italiana è fatta bene, ma spesso quella inglese spesso è più aggiornata e a volte più dettagliata.

Sì infatti questa pagina spiega molto bene cosa fare e non l'ho trovata in italiano!

m'accollo al topic.

domanda, ma arch, durante l'installazione, non dovrebbe, superata la fase di configurazione, dare un 'mkinitcpio' o simile?

perché non mi pare di leggere nulla di simile, e difatti dopo non parte, non riesce a montare i fs in LVM

ovviamente ho seguito questi 2 punti:

Citazione
Assicurarsi di avere la riga USELVM="yes" in /etc/rc.conf, se la directory radice del sistema si trova su un Volume Logico. (Configure System)
Aggiungere lvm2 alla lista HOOKS in /etc/mkinitcpio.conf subito prima di filesystems così il kernel sarà in grado di accedere ai Volumi Logici in avvio del sistema. (Configure System)

al boot: ERROR: unable to determine major/minor number of root device '/dev/mapper/archlaptop-rootfs'.

Certo che sì. Non lo ha fatto? o.O Di che data è lo snapshot?

cicco fai una cosa:
Codice: [Seleziona]
pacman -S bootchart
Poi cosa usi, grub 1 o grub 2?

grub 1:
con un editor di testo apri /boot/grub/menu.lst
vai alla riga kernel ed aggiungi init=/sbin/bootchartd
Deve venire tipo così:
Citazione
# (1) Arch Linux Bootchart
title  Arch Linux
root   (hd0,0)
kernel /vmlinuz-linux root=/dev/disk/by-uuid/d531ff5b-de65-499a-9942-d18682375163 ro quiet init=/sbin/bootchartd
initrd /initramfs-linux.img

grub 2:
per renderlo semi-permanente fai quanto sopra ma con /boot/grub/grub.cfg
Se vuoi renderlo davvero permanente chiedi.

Poi avvia arch, apri un terminale in una cartella (io ho creato "bootchart" sulla scrivania per farlo) e dai
Codice: [Seleziona]
bootchart-render

Poi mettimi qua i seguenti:
/etc/rc.conf
/etc/inittab
/etc/rc.sysinit

Le modifiche al grub ti fanno partire bootchart all'avvio, bootchart serve per misurare i tempi di avvio, qua la wiki:


Modifica la riga demoni in rc.conf da:
DAEMONS=(@hwclock @syslog-ng dbus network netfs crond gdm @sensor)

a:
DAEMONS=(hwclock syslog-ng dbus @gdm @sensor @crond @network @netfs)

Per la parte di rete si potrebbe anche commentarla tutta con # e demandare tutto al gestore di rete, ormai il suggerimento (ed il futuro andazzo) è quello.
