Currently, ps command can not support argument:
(But following usage is in manual)
| # ./runc ps 123 -ef
| Incorrect Usage.
|
| NAME:
| runc ps - ps displays the processes running inside a container
|
| USAGE:
| runc ps [command options] <container-id> [ps options]
|
| OPTIONS:
| --format value, -f value select one of: table or json
|
| flag provided but not defined: -ef
| #
Instead of using odd command like:
| # ./runc ps -- 123 -ef
We can make it seems little better:
| # ./runc ps 123 -- -ef
| UID PID PPID C STIME TTY TIME CMD
| root 29046 29038 0 11:18 pts/2 00:00:00 sh
| #
This patch also fixed manual which can not working in current
code.
Closes#788

1. According to docs of Cmd.Path and Cmd.Args from package "os/exec":
Path is the path of the command to run. Args holds command line
arguments, including the command as Args[0]. We have mixed usage
of args. In InitPath(), InitArgs only take arguments, in InitArgs(),
InitArgs including the command as Args[0]. This is confusing.
2. InitArgs() already have the ability to configure a LinuxFactory
with the provided absolute path to the init binary and arguements as
InitPath() does.
3. exec.Command() will take care of serching executable path.
4. The default "/proc/self/exe" instead of os.Args[0] is passed to
InitArgs in order to allow relative path for the runC binary.

Added a unit test to verify that 'cpu.rt_runtime_us' and 'cpu.rt_runtime_us'
cgroup values are set when the cgroup is applied to a process.

before trying to move the process into the cgroup.
This is required if runc itself is running in SCHED_RR mode, as it is not
possible to add a process in SCHED_RR mode to a cgroup which hasn't been
assigned any RT bandwidth. And RT bandwidth is not inherited, each new
cgroup starts with 0 b/w.

There's no point in changing directory here. Syscalls are resolved local
to the linkpath, not to the current directory that the process was in
when creating the symlink. Changing directories just confuses people who
are trying to debug things.

Comparisons with paths aren't really a good idea unless you're
guaranteed that the comparison will work will all paths that resolve to
the same lexical path as the compared path.

This is a very important testcase, as certain permission issues can
arise if we don't test this automatically.

Argument of "ps options" for ps command is a optional parameter.
Should use [] instead of <> in manual.

This removes the use of a signal handler and SIGCONT to signal the init
process to exec the users process.

Prior to this change a cgroup with a `:` character in it's path was not
parsed correctly (as occurs on some instances of systemd cgroups under
some versions of systemd, e.g. 225 with accounting).
This fixes that issue and adds a test.
