* automount: check for recursive automountSascha Hauer2014-07-031-1/+9
| | | | | | | | | | | | | automount_mount calls run_command which may trigger an automount again. This results in an endless loop. A simple way to trigger this is: mkdir /x; automount /x false; cd /x; something Use a static variable to detect if we are currently in automount_mount() and bail out if we are.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compared to devfs_add_partition which adds a single partition devfs_create_partitions creates several partitions at once. One nice benefit is that this simplifies appending partitions because the start of the latter partition doesn't need to be specified explicitly. Also dev_add_bb_dev() is called by the new helper if the bbname is specified for a partition. Note that adding partitions is also more flexible now (also via devfs_add_partition) because negative values for offset and size now have a proper meaning instead of creating broken partitions.
