Hi List,
I have an app that uses linux's clone() syscall (with the CLONE_NEWNS flag).
I need to migrate this app to freebsd.
Is there similar functionality in freebsd? For what I read fork() and rfork()
wont do the trick. I need the children to have their own private mount
namespaces.
I am afraid that FreeBSD doesn't have this capability.
There is a single mount namespace per whole system image.
BTW, I am intrigued, in what situations this flag is useful?
See his other email for more detail on what he wants.
I have not heard of this before and you are correct in that we do not
have this capacity.
I have considered giving jails the capacity to have their own 'real /'
i.e. have a totally different filesystem name space (not just a
chroot). Then when the jail is removed then namespace would
disappear. but that's sort of different.
