sys-apps/rescan-scsi-bus doesn't work with the obsolete /proc/scsi # rescan-scsi-bus.sh Error: SCSI subsystem not active A workaround is to turn CONFIG_SCSI_PROC_FS on. I ran into this since the new sys-apps/sg3_utils/sg3_utils-1.24 requires rescan-scsi-bus. I took a short look at the script. It's hardcoded to check if /proc/scsi is a directory. It looks like it has support for sysfs but still rely on at least this point on /proc/scsi. So, I beliefe at least we should do a warning in the ebuild. But maybe someone has the time and intrest to really fix this.
fixed in cvs.
