12784	"Use of ""cp -p"" on a tmpfs is broken in recent versions coreutils on solaris"	anonymous		"When running bootstrap.sh, under the circumstances outlined below
it'll fail to copy ""b2"" to ""jam0"" with the error:

{{{
preserving permissions for 'bin.solarissparc/bjam': Operation not applicable
}}}

This happens when:

* Building on solaris
* Using the gcc toolset (unsure whether this is related)
* umask is set to 002 (works fine with 022)
* The GNU version of ""cp"" is the first one found in PATH
* That version of ""cp"" was built against a new enough version of coreutils

I was able to work around the problem like this:

{{{
mkdir -p /tmp/dirty_hack
cd /tmp/dirty_hack
ln -s /usr/bin/cp
PATH=/tmp/dirty_hack:${PATH} ./bootstrap.sh ...bootstrap flags...
PATH=/tmp/dirty_hack:${PATH} ./bjam ...bjam flags...
}}}

At a minimum it might be a good idea to allow a configurable variable akin to JAMSHELL for what string to use to copy files & preserve permissions.
