The scstadmin manuals still describe the 2.0 parser, a database backend
and SysV-only service integration. They omit current ALUA operations
and call -check_config an offline check even though it reads live sysfs.
Commit 3a8d70b166 ("- Remove old scst_db stuff which no longer
works with even procfs.") removed the database implementation. The
current grammar and apply order live in scstadmin.sysfs/scstadmin,
while SCST/SCST.pm consumes the kernel-provided sysfs metadata.
Document the current commands, quoting, comments, DEVICE references
and systemd environment handling. Keep deprecated-format conversion,
but explain that it reconciles live state. Mark conversion, checking,
examples, installation and service operations with their root, sysfs
and exported-storage effects.
