Where in Slackware is the umask set????

I have seen in the past that it is suggested that a umask 022 be set at
the begining of each rc. script.

Is this still an issue. Why or why not???

As the first thing, init sets umask(022). It's hardcoded in the init binary.
Maybe you remember something like SunOS 4 which created world writable wtmp
because of umask 0.

On my boxen that might be edited. To find out, like so:
grep -r -i umask /etc 2>/dev/null

Might be a good idee, though it defaults to that.


I read something about that, some time ago. I don't think this post was
the one i read then. However it basically explains the same thing: http://lists.suse.com/archive/suse-security/2001-Jun/0197.html


Well, that may be. However it's set in kernel (2.4.24) as well:

$ grep -A5 INIT_FS ./include/linux/fs_struct.h
#define INIT_FS { \
ATOMIC_INIT(1), \
RW_LOCK_UNLOCKED, \
0022, \
NULL, NULL, NULL, NULL, NULL, NULL \ }

Haven't worked with SunOS 4.x lately, didn't know that though. Thanks.
