I installed arch64 from bootable iso and then upgraded whole system with packages from archlinux.org. During update kernel it started complaining: "cannod load shared object - no such file" about libraries: libblkid.so.1 and libreadline.so.5 Then later on the system freezed. I rebooted, and I couldn't boot with arch kernel ( pacman didn't make proper image yet ), my own kernel too ( after initrd removal: kernel panic - not sync - cannot find init - try "init=" parametrer ) and of course my own kernel started be I see that libraries are divided between /lib and /lib64 dirs and /lib64 contains missing two: libblkid.so.1 and libreadline.so.5 So maybe you have suggestions what to do now or before ;) Best regards, thanks to the devs Robert
