yes, if /dev/net/tun is not existing, the patched script will just create it
correctly.

agreed...

yes, that seems to be obvious, but i can't test that special case. the same
goes with the symlink case. am i fully sure what the snipped want to resolve?
let me try to sum up:
if dev cannot be read and written do:
1 modprobe driver (shouldn't there be a condition if already
loaded?)
2 if dev is a symlink to wrong location fix symlink
3 wait for 10 sec for the dev to show up, check by r/w
4 if dev (still) doesn't exists create it
so i would suggest to move the loop as in your patch 2 but i would suggest to
use the same check of existence of the dev for all 3 cases, maybe just -e to
keep the script simple (-c would be better but then you have to remove the file
to use mknod and it does not work for the symlinkcase, still it would repair
systems where the initial bug happened already).
