Hi All,
I used the tip given on the list to make the unionfs patch compatible
with vserver (adding a lot of NULLs as parameter to the appropriate
unionfs calls), but it seems as this was not a really goor deal.
I mounted an overlay ontop of a read-onle directory and got kernel
oopses when I wanted to access files on the overlayed system.
Everything was done in host namespace witout any guetsts running.
So I am interessted in version of working vserver/unionfs or people
having an idea about the oops.
TIA
Oliver
