[LTP] [PATCH v2] Add containers/share to PATH when call init_ltp_netspace

[Petr Vorel]

Hi Wei,

> When run single test case use command such as:
> LTP_SHELL_API_TESTS=shell/net/tst_rhost_run.sh make test-shell
> Error msg such as "ns_create: command not found" will popup, so
> need update PATH before call ns_create etc..

Once fixed, it should be here:

This is not acceptable. The path should go to the test itself (tst_net.sh should
be either proper installed, then it expect ns_clone and other binaries to be
properly in /opt/ltp/testcases/bin and $PATH set to it. Or, if it's used for a
development, user is required to set the correct $PATH already.)

The reason why it should be in tst_rhost_run.sh is to allow testing instead of
make install. But user still needs to run make in required directories to have
required binaries at least compiled (if not installed).

NOTE: there are only 2 network shell API tests and the other tst_ipaddr_un.sh
does not use namespaces, that's why it goes just to this test.

This is wrong:
s/ns_ifmov/ns_ifmove/

(copy & paste is your friend to prevent silly errors)

Kind regards,
