Re: Linux compatibility and /dev/null

 What gives?  ls -l /dev/null says:
 
   crw-rw-rw-  1 root  wheel2,   2 Oct  9 12:45 /dev/null

As it should.

 That's groovy.  But what about /compat/linux/dev/null?
 
   -rw-r--r--  1 root  wheel  0 Oct  2 17:59 /compat/linux/dev/null

Huh??! A _file_??! It should be a device!

 Hmm???  Doing chmod 666 /compat/linux/dev/null fixes the problem.

Temporarily only. A better workaround is rm /compat/linux/dev/null;
mknod /compat/linux/dev/null c 2 2 root:wheel. With your solution,
that file may fill up with unwanted junk.

 This looks like a bug in the linux-base port.  I'll file a PR.

Indeed. Good move.

Linux compatibility and /dev/null

[Robert Withrow]

Hi:

I was trying to get my linux-mozilla-1.1 to spawn off acroread when
I click on PDF links, but I kept getting this:

  /usr/local/bin/acroread5: /dev/null: Permission denied

I played with the acroread5 script and added, at the beginning,

  echo hi  /dev/null

and got:

  + echo hi
  /home/bwithrow/bin/acroread5: /dev/null: Permission denied

What gives?  ls -l /dev/null says:

  crw-rw-rw-  1 root  wheel2,   2 Oct  9 12:45 /dev/null

That's groovy.  But what about /compat/linux/dev/null?

  -rw-r--r--  1 root  wheel  0 Oct  2 17:59 /compat/linux/dev/null

Hmm???  Doing chmod 666 /compat/linux/dev/null fixes the problem.

This looks like a bug in the linux-base port.  I'll file a PR.

The port already does this:

#
# Make sure we have a /dev/null in the chrooted environment.
${MKDIR} ${LINUXBASE}/dev
${RM} -f ${LINUXBASE}/dev/null
mknod ${LINUXBASE}/dev/null c 2 2
${CHMOD} 666 ${LINUXBASE}/dev/null

I don't know why yours didnt do that, but it certainly should have.

Definitely wrong.

Why not just remove it?  If you remove it, the device will be
looked up in the system directory instead, and it will get the
real /dev/null instead of the compat version.  There aren't
supposed to be semantic differences between FreeBSD and Linux,
for /dev/null.

It sounds instead like there is a problem with the union of /
and /compat/linux for  xxx redirects... certain kinds of
opens.

I re-installed linux_base and that *did* remove it.  And, as Terry
suggests, acroread works fine without it.  In fact there is no
/compat/linux/dev directory at all after the reinstall.

I don't have a clue how that file got created in the first place, except
to guess that it is a side effect of installing some port.

Also, Kris points out that the Makefile for the linux_base port has
this in the do-install section

# Make sure we have a /dev/null in the chrooted environment.
@${MKDIR} ${LINUXBASE}/dev
@${RM} -f ${LINUXBASE}/dev/null
@mknod ${LINUXBASE}/dev/null c 2 2
@${CHMOD} 666 ${LINUXBASE}/dev/null

But, as I said above, there is no /compat/linux/dev after the install,
so you can color me confused.
