These options allow to specify alternative groups. The command
su(1) has to be executed by root. The implementation is based on
Fedora runuser(1) command.
For example:
# su --group=kzak --supp-group=uuidd -
# id
uid=0(root) gid=1000(kzak) groups=0(root),985(uuidd),1000(kzak)
non-root user:
$ su --group=kzak -
su: only root can specify alternative groups

setarch: do not use -1 as array index [cppcheck]
I'm not sure having /usr/local in _PATH_DEFPATH_ROOT and even putting it
in front is such a good idea though. /usr/local might be on NFS so could
prevent root from logging in if the network is down.
files and we bootstrap the rest from gnulib, gettext, etc.
* README-cvs: New file.
* bootstrap: New file.
* bootstrap.conf: New file.
* .x-sc_trailing_blank: Remove config-log, .gdb-history. Add .po.
* configure.ac (AC_PREREQ): Move here from m4/*.m4, for benefit
of gnulib-tool.
(gl_DEFAULT_POSIX2_VERSION, gl_USE_SYSTEM_EXTENSIONS, gl_PERL):
(gl_IGNORE_UNUSED_LIBRARIES): Remove; now done by gnulib.
(gl_EARLY): Add.
(gl_MACROS): Call just after gl_EARLY, just for clarity.
* src/c99-to-c98.diff: Remove patch to ls.c; no longer needed.
* src/kill.c (strtoimax): Remove decl.
* src/ls.c: Include "wcwidth.h" instead of rolling it ourselves.
* src/wc.c: Likewise.
* src/ls.c (sort_files): Rewrite to avoid need for C99-style
declaration, so that we don't need to patch this file.
* src/printf.c (strtoimax, strtoumax): Remove decls.
* src/su.c: Include getpass.h.
(getpass): remove.
* src/system.h: Include mempcpy.h, stpcpy.h, strpbrk.h.
Include inttypes.h unconditionally; remove decls it handles.
* lib/Makefile.am: include gnulib.mk, so that we can remove most of
this file.
(AM_CPPFLAGS): Don't mention -I$(srcdir), since that's now done
for us.
(noinst_LIBRARIES, LDDADD, DEFS): Remove.
(libcoreutils_a_SOURCES): Trim down greatly, just to the files
that aren't in gnulib.
Remove defns gnulib does for us.
* m4/check-decl.m4 (gl_CHECK_DECLS):
Don't include stdio.h, string.h, stdlib.h, unistd.h, sys/time.h,
time.h. Use AC_CHECK_DECLS_ONCE for free, getenv, geteuid, getlogin,
getuid, lseek, malloc, memchr, realloc. Don't check for getutent,
memrchr, nanosleep, stpcpy, strndup, strnlen, strstr, strtoul,
strtoull.
(_gl_DECL_HEADERS): Remove; all uses removed.
* m4/jm-macros.m4 (gl_MACROS): Move AC_PREREQ into configure.ac
for the benefit of gnulib-tool. Call gl_INIT.
Do not call or require macros that gnulib will handle for us.
Don't check for fchmod, hasmntopt, isascii, lchown, listmntent,
mempcpy, realpath, wcrtomb, tzset.
(gl_CHECK_ALL_HEADERS): Don't check for sys/statvfs.h, sys/vfs.h,
sys/mount.h.
(gl_CHECK_ALL_TYPES): Require AC_TYPE_UNSIGNED_LONG_LONG_INT.
Don't check for struct stat.st_blksize.
Don't require AC_STRUCT_ST_DM_MODE, gt_TYPE_SSIZE_T,
gl_AC_TYPE_UINT32_T, gl_AC_TYPE_UINTMAX_T, gl_AC_TYPE_UINTPTR_T,
gl_AC_TYPE_UNSIGNED_LONG_LONG.
* m4/prereq.m4 (gl_PREREQ): Require gl_FUNC_XFTS, gl_ROOT_DEV_INO.
Don't require macros that gnulib does for us.
* m4/stat-prog.m4 (cu_PREREQ_STAT_PROG): Don't check for
sys/sysmacros.h. Don't check for statvfs. Use AC_CHECK_HEADERS_ONCE
for netinet/in.h, nfs/nfs_clnt.h, nfs/vfs.h.
Don't require gl_AC_TYPE_LONG_LONG, gt_HEADER_INTTYPES_H.
the callee doesn't have to count 'em. All callers changed.
Don't allocate more space for the arg vector than we'll need.
Use memcpy to copy the args rather than rolling our own loop.
Use size_t for sizes.
(fast_startup, simulate_login, change_environment, log_su,
correct_password, restricted_shell, main): Use bool for booleans.
(longopts): Don't assume change_environment is an int.
Use NULL, not 0, for pointers.
(xsetenv): New function, replacing xputenv and concat.
All callers changed.
(elements): Remove; no longer needed.
(log_su, correct_passwd, main): Prefer !x to x==NULL.
(log_su): 2 -> STDERR_FILENO.
(modify_environment, main): Don't assume that getenv's returned value
has an indefinite lifetime.
(modify_environment): Allocate a larger environ.
(main): Remove an impossible 'case 0'; if it happens now, it'll
get diagnosed. Don't assume getpwnam results outlive endpwent.
Check for null or empty pw_name, pw_dir and for null pw_passwd.
of 2003-09-19. Now, AUTHORS is a comma-separated list of strings.
Update the call to parse_long_options so that `AUTHORS, NULL' are the
last parameters.
* src/true.c (main): Append NULL to version_etc argument list.
* src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
(main): Use close_stdout via atexit.
Now `su --version > /dev/full' fails, as it should.
Somehow, the change of 2000-05-07 that purports to fix this
was not checked in.
