unshare: add --mount-proc for pid namespaces

Based on patch from Mike Frysinger <vapier@gentoo.org>.

Mike Frysinger wrote:
 When it comes to pid namespaces, it's also useful for /proc to reflect
 the current namespace.  Again, this is easy to pull off, but annoying
 to force everyone to do it themselves.  So let's add a --mount-proc to
 do the magic for us.  The downside is that this also implies creating
 a mount namespace as mounting the new pid namespace /proc over top the
 system one will quickly break all other processes on the system.

10 years agounshare: add --fork options for pid namespaces
Mike Frysinger [Fri, 28 Jun 2013 00:04:58 +0000 (20:04 -0400)] 
unshare: add --fork options for pid namespaces

The ability of unshare to launch a new pid namespace is a bit limited.
The first process in the namespace is expected to be the "init" for it.
When it's not, you get bad behavior.

For example, trying to launch a shell in a new pid namespace fails very
quickly:
$ sudo unshare -p dash
# uname -r
3.8.3
# uname -m
dash: 2: Cannot fork
# ls -ld /
dash: 3: Cannot fork
# echo $$
1324

For this to work smoothly, we need an init process to actively watch over
things.  But forcing people to re-use an existing init or write their own
mini init is a bit overkill.  So let's add a --fork option to unshare to
do this common bit of book keeping.  Now we can do:
$ sudo unshare -p --fork dash
# uname -r
3.8.3
# uname -m
x86_64
# ls -ld /
drwxr-xr-x 22 root root 4096 May  4 14:01 /
# echo $$
1
