Note to self: xen and modules

My brain is rotten. everytime the kernel on my dom0 gets updated, even its only minor, the domUs start going all crazy, with  random dpkg errors, services that terminate at random, fscks going horribly wrong. but they do it with enough delta in between, so that i never suspect the kernel upgrade.  So me dumbfuck spends the better part of an hour investigating the problem and of course finding no solution whatsoever.

solution: once and for ever

- tar gzip all modules inside of  /lib/modules/kernelXXXX and sftp to domU

- unrar and copy.

- reboot
