What is "misguided and uninformed opinion"? That you can't with ConfigFS
serve real life needs for target driver developers and can't create
targets for hardware target ports from withing the kernel and instead
enforce users to clumsy workarounds to somehow magically know their
names to manually perform "mkdir target_name"?
The same problem exists for all other objects where you need to create
ConfigFS entries (directories), like for per-session/per-initiator
statistics or default ACLs.
ConfigFS is just too simple to serve real life needs of a SCSI target
subsystem.
