- The applets currently marked to need the suid bit are:
+ The applets which require root rights (need suid bit or
+ to be run by root) and will refuse to execute otherwise:
+ crontab, login, passwd, su, vlock, wall.
- crontab, dnsd, findfs, ipcrm, ipcs, login, passwd, ping, su,
- traceroute, vlock.
+ The applets which will use root rights if they have them
+ (via suid bit, or because run by root), but would try to work
+ without root right nevertheless:
+ findfs, ping[6], traceroute[6], mount.
+
+ Note that if you DONT select this option, but DO make busybox
+ suid root, ALL applets will run under root, which is a huge
+ security hole (think "cp /some/file /etc/passwd").
