Well, what I am seeing is the /dev/null changing permissions _after_ the build/installation of the jail. That is, either it is changing at some random time while the jail is running, or it changes after the jail is stopped, then started again. And it happens over and over, that is, if I reset it to 0666, at some time in the future it will revert to 0600 Any idea why ? > >Hi, > >I've experimented this when I've rebuilt my world just after the announce >of >4.7-RC. mergemaster asked me if I wanted to run MAKEDEV since it had >changed. >I think it's this which broke up /dev/null, then i re-runed sh ./MAKEDEV >and >everything was fine :) > >I don't know if my second run of MAKEDEV solved the problem (maybe it was >fixed >before I run it again, I don't exactly know) > >-- Aurélien > >On Thu, Oct 03, 2002 at 12:25:15PM -0700, Firsto Lasto wrote: > > > > If you run a jail, and inside that jail is a /dev with the file >/dev/null > > in it, the normal 0666 permissions of /dev/null will often get changed >to > > 0600. > > > > I cannot see any reason why this would happen - I thought maybe there >was > > something in /etc/rc that would do it, but there is not.
