Hi, I got a quick question because I fucked up and think quite a bunch of other people I have read about here did as well.
I read in a couple of postings that people like to mount their root partition as read-only, I followed that since it prevents accidents in combination of 'rm' with '*' and <Return> as well as fscks of / By accident I stumbled about the the permissions of /dev/tty* today and found that they get changed from crw-rw-rw- 1 root wheel 5, 14 Dec 30 11:39 ttyp to crw--w---- 1 user tty 5, 14 Dec 30 12:11 ttype when a user has them in use (or root). Obviously they can't get chmod/chown if / is ro, thus ripping a huge local security hole into the system. Whey I mailed here is: Is it good practice at all to mount / read-only? Is it only an issue when using X? Am I wrong and this is no security risk? Reasons? Regards, ahb In case this is all nonsense (I didn't think it is), sorry for the noice
