Hello Jon,

thanks for your reply.

Um, I thought we do that in the update.sh of every Core Update that involves a kernel update?

When multiple Core Updates are available, Pakfire will currently download them all before applying
them sequentially. On systems with very tight disk space, this can indeed cause trouble, since the
more Core Updates they lag behind, the greater is the amount of disk space necessary for upgrading.

I guess it makes sense to raise this issue and the general question whether we should ship initial
ramdisks or generate them on the target systems (the former has quite some impact on Core Update
sizes) in the August telephone conference.

Any thoughts?

Thanks, and best regards,
Peter Müller
