>Environment:
FreeBSD 2.0.5
>Description:
mtree(8) seems to change modes and owners of files not contained in
the description file if files with the same last component are
described elsewhere in the description.
This was originally discovered when it appeared that a
slightly modified BSD.local.dist and BSD.usr.dist were fighting
over the permissions of /usr/local/bin when BSD.usr.dist contained
no specification for them.
>How-To-Repeat:
% su root
# cat > /tmp/mtree
# This is a cut-down version of BSD.usr.dist
/set type=dir uname=bin gname=bin mode=0755
. uname=root gname=wheel
bin
..
/set type=dir uname=bin gname=bin mode=0755
include
..
/set type=dir uname=bin gname=bin mode=0775
# you can get around the problem by putting "ignore" on the local line.
local mode=0775
..
..
^D
# mkdir /tmp/test
# cd /tmp/test
# mtree -e -U -f ../mtree -p /tmp/test
(mtree creates 3 directories, bin, include, and local, as it should)
# mkdir local/bin local/include local/lib local/libexec
# chmod 0 local/*
# chown root.wheel local/*
(these 4 directories are NOT described in the mtree description)
# mtree -e -U -f ../mtree -p /tmp/test
local/bin:
user (3, 0, modified)
gid (7, 0, modified)
permissions (0755, 0, modified)
local/include:
user (3, 0, modified)
gid (7, 0, modified)
permissions (0755, 0, modified)
# ls -l local
total 8
drwxr-xr-x 2 bin bin 512 Jul 18 20:23 bin
drwxr-xr-x 2 bin bin 512 Jul 18 20:23 include
d--------- 2 root wheel 512 Jul 18 20:23 lib
d--------- 2 root wheel 512 Jul 18 20:23 libexec
Why is it changing modes and owners on these files which have no specified
permissions? It seems to be using the permissions for ./bin and ./include
to change ./local/bin and ./local/include .
>Fix:
You can work around this by putting "ignore" on directories whose
substructure you don't want changed.
