All flames welcome as a learning experience.... ;-)
I am currently running a -current on a group of machines where I
work. I decided to use the MD5 libscrypt passwords, and noticed something
strange in the daily output e-mail. When the MD5 passwords are used the
daily output e-mail fails to truncate the encrypted passwd from the
/etc/master.passwd file before e-mailing out the diffs. This is the case
even on a machine which was built today. I haven't seen any info on
-current about it so I thought I would bring it up.
I also wrote and attached small patch to take care of the issue in
the short term. all it does is change:
diff $bak/master.passwd.bak /etc/master.passwd |\
sed 's/^\([<>] [^:]*\):[^:]*:/\1:(password):/'
to:
diff $bak/master.passwd.bak /etc/master.passwd |\
sed 's/^\([^:]*\):[^:]*:/\1:(password):/'
My logic could be messed up, so if there are any issues that I
overlooked in the patch I would love to hear about them. I thought it
might be a good thing to take care of quick before -RELEASE (yea!)
Thanks all...
