I made a mistake when using cpio command, I forgot to specify parameter: --no-absolute-filenames, so some files in / were overwrote, after the following command was executed:
cpio -idmv < files.cpio
When I try to reboot my Ubuntu 12.04, after selected kernel listed in Grub page, then it wouldn't startup.
it shows like this:
init started: Busybox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4.1) *Starting AppArmor profiles *Mounting securityfs on /sys/kernel/security... Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox Skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd [OK] * Starting portmap daemon... [OK] rm: cannot remove '/var/lib/urandom/random-seed':Read-only file system Please press Enter to activate this console.
can anyone give me some suggestions to figure this problem out?
Thank you all.
