Congratulations to sunckell and Bernd for guessing the right answer. Additionally to the blog comments (which I delayed through moderation to give […]

Update: see LART of the day – the solution for the solution. % cat foo.c int main() { return 0; } % gcc foo.c foo.c:1: fatal error: can’t open /tmp/ccxgyEhb.s for writing: Permission denied compilation terminated.

After migrating one of my 32bit systems to a fresh 64bit system I suddenly couldn’t use this Remote Console feature any longer. The error message was (leaving […]

Live-initramfs is a fork of Ubuntu’s casper for use within Debian. Nowadays several Debian based live systems are using live-initramfs to build an initramfs suited to boot live systems. Besides debian-live and all its users that’s at least Grml (and its derivates) and FAI. I’m maintaining live-initramfs for Grml – so I know the limitations […]

But whereas I want to use that for all my official Debian packages I still want to use $DEBEMAIL=mika@grml.org for my grml related packages.
