I can ask.

AFAIK it is a compile time option only, so you'd need to rebuild.Â

yeah, i avoid these things if i can, it's very time hungry :-) And i've never built Xen.

Of course my problem is gonna be that /run is destroyed at every reboot so i'll have to do everything manually...Â

Somehow i knew i should have stayed with my old Alpine and Xen.Â

13MB is pretty meagre for /var/run though, on Debian mine is a 700MB
ramdisk for example...

Isn't /var/run is for PIDs and named pipes mostly, so I'm not sure it needs to be big either.

As for Alpine, it is a pretty sleek running distro... It is only dom0 for me and runs on something like 256MB or maybe 512MB of RAM, the rest being available to domUs.

But is it really useful to have the kernel available for boot in a ramdisk ? After boot it will be in the domU RAM anyway, no ?
