As of ISO 2014.11.01 attempts to install packages within the live system itself can cause complete system failure, apparently due to problems affecting device mapper.

The problem is a regression that can't be seen with ISO 2014.10.01. It doesn't always appear and I couldn't find out the exact conditions. But it seems the number / volume of packages that are about to be installed has to exceed some kind of threshold. Also, it doesn't affect running pacstrap the usual way.

Attaching journalctl output from a KVM/QEMU instance (behaviour is the same booting "bare metal", though).

The cowfile has a default size of 256MB now. Probably that filled up. Try to boot with cowfile_size=2G and try again.

Any attempt to do so (2g, 1g, 256[m]b) results in kernel panic, the last line before reading /init: line 48: arithmetic syntax error

I can not reproduce this and the parameter works as expected for me. So no idea what is wrong on your side... -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Chris get my mail address: */=0;b=c[a++];) putchar(b-1/(/* gcc -o sig sig.c && ./sig */b/42*2-3)*42);}
