// Notes: Automatic and manual roots have the following relationship.
|
|
//
|
|
// 1. If a root is purely manual (e.g. not in Gibraltar), then
|
|
// addition is only by the user, and deletion really deletes
|
|
// the root. A placeholder is not maintained in the vroot
|
|
// list.
|
|
//
|
|
// 2. If a root is purely automatic, then it is always used,
|
|
// and is added and removed in complete sync with Gibraltar.
|
|
//
|
|
// 3. If a root was manual and was automatically added, the 'in-use'
|
|
// state from pure-manual mode is maintained.
|
|
//
|
|
// 4. If a root was automatic and was manually added, it is
|
|
// always set to 'in-use'.
|
|
//
|
|
// 5. If a root was both manual and automatic and automaticlly
|
|
// deleted the deletion occurs. Period.
|
|
//
|
|
// 6. If a root was both manual and automatic and manually deleted,
|
|
// the root is kept as an out-of-use placeholder.
