Nowadays scst_local doesn't need anymore auto closing sessions on target unregistration. Moreover, it can lead for it to the following Oops: BUG at /home/bart/software/scst.git/scst/src/scst_targ.c:6293 ------------[ cut here ]------------ kernel BUG at /home/bart/software/scst.git/scst/src/scst_targ.c:6293!

This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files.
