registry: add comment explaining workflow to make store_keys safe w/o transactions
/*
* Make the store operation as safe as possible without transactions:
*
* (1) For each subkey removed from ctr compared with old_subkeys:
*
* (a) First delete the value db entry.
*
* (b) Next delete the secdesc db record.
*
* (c) Then delete the subkey list entry.
*
* (2) Now write the list of subkeys of the parent key,
* deleting removed entries and adding new ones.
*
* (3) Finally create the subkey list entries for the added keys.
*
* This way if we crash half-way in between deleting the subkeys
* and storing the parent's list of subkeys, no old data can pop up
* out of the blue when re-adding keys later on.
*/
The workflow is going to be modified to meet this agendain the next commits.
