From what I see in the source code of useradd.c in shadow, the feature is compiled conditionally, #ifdef ENABLE_SUBIDS. It may be that RHEL, or your version, doesn't build with that option; I ignore it, I'm a Debian user. alx@debian:~/src/shadow/shadow/master$ grep -rl add.subids.for.system man/useradd.8.xml po/fr.po tests/run_all.coverage tests/run_all src/useradd.c alx@debian:~/src/shadow/shadow/master$ grep -rn -C1 add.subids.for.system src/ src/useradd.c-954-#ifdef ENABLE_SUBIDS src/useradd.c:955: (void) fputs (_(" -F, --add-subids-for-system add entries to sub[ud]id even when adding a system user\n"), usageout); src/useradd.c-956-#endif -- src/useradd.c-1245-#ifdef ENABLE_SUBIDS src/useradd.c:1246: {"add-subids-for-system", no_argument,NULL, 'F'}, src/useradd.c-1247-#endif Cheers, Alex -- <https://www.alejandro-colomar.es/>
