Maxime Henrion d786139c76 Rework the kernel environment subsystem. We now convert the static ... environment needed at boot time to a dynamic subsystem when VM is up. The dynamic kernel environment is protected by an sx lock. This adds some new functions to manipulate the kernel environment : freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be called after every getenv() when you have finished using the string. testenv() only tests if an environment variable is present, and doesn't require a freeenv() call. setenv() and unsetenv() are self explanatory. The kenv(2) syscall exports these new functionalities to userland, mainly for kenv(1). Reviewed by: peter		2002-04-17 13:06:36 +00:00
