qualche idea?
3 minuti e rotti di boot son davvero troppi. prima ce ne mettevo 30

nel boot.log ho trovato questo:

Codice: Seleziona tutto

[ TIME ] Timed out waiting for device dev-disk-by\x2duuid-72b18fd9\x2de2e3\x2d415c\x2d8a29\x2d29bb9a8a98f6.device.

e cat /etc/fstab

ok. l'UUID della swap era sbagliato.
però sono ancora 1 minuto e 18 sec di boot.
altre idee?
