On a system restore from a tar archive sudo won't work. Says
/usr/bin/sudo needs to be owned by 0 with the suid bit set. Root
owns the file and is 0. Looking at a working system directory list shows
-rwsr-xr-x. 1 root root 57456 Aug 16 20:00 su
---s--x--x. 1 root root 202872 Jul 24 20:00 sudo
How does that s bit get set?
man chmod, paragraph 2
The error message is about an suid bit while the man page talks about
setuid, trying it works. Not a clear extension over the old 777.
# chmod 4755 /bin/su
# chmod 4111 /bin/sudo
The suid (setuid), sgid (setgid), and sticky bit are an additional
3 binary bits above the owners permissions. 4=suid, 2=sgid, 1=sticky
