|
|---|
| 49 | # Testing:
|
|---|
| 50 | # * Should fail if the configuration file is missing or missing INSTALL_DIR or
|
|---|
| 51 | # INSTALL_VER entries.
|
|---|
| 52 | # * vboxadd, vboxsf and vboxdrmipc user groups should be created if they do not exist - test
|
|---|
| 53 | # by removing them before installing.
|
|---|
| 54 | # * Shared folders can be mounted and auto-mounts accessible to vboxsf group,
|
|---|
| 55 | # including on recent Fedoras with SELinux.
|
|---|
| 56 | # * Setting INSTALL_NO_MODULE_BUILDS inhibits modules and module automatic
|
|---|
| 57 | # rebuild script creation; otherwise modules, user, group, rebuild script,
|
|---|
| 58 | # udev rule and shared folder mount helper should be created/set up.
|
|---|
| 59 | # * Setting INSTALL_NO_MODULE_BUILDS inhibits module load and unload on start
|
|---|
| 60 | # and stop.
|
|---|
| 61 | # * Uninstalling the Additions and re-installing them does not trigger warnings.
