Mac OS X and Arch: guid and suid bits

posted Feb 10, 2009, 3:14 PM by Jade Rubick

From Alex K:
After spending about 3 hours looking into it, compiling half the gnu tools from scratch I finally fixed arch on my machine. After I compiled the latest version of tar I noticed that rather then giving an error it simply said 'permission denied'. Doing some more googling it seems that the latest security update for Panther has disallowed the user from setting the setgid bit. It's the only UNIX to do this and the move was praised in some security researcher's blog. By simply

sudo tla replay

the problem was resolved.


sudo'ing the replay command broke all the tla commands for the normal user but chowning the {arch} directory back to alexk seems to have fixed everything.
