           Summary: Busybox flqsh commands conflict with those from mtd-
                    utils
           Product: buildroot
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: buildroot at istwok.net
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


The new busybox-1.16.x.config enables some flash related commands that can
conflict with the same commands in the mtd-utils package.  If both are enabled,
the busybox binary gets overwritten by the mtd-utils binary during the build.

That is how we normally do it (E.G. let the big versions "win" if both are
enabled). What would you suggest we do instead?

The bigger version winning is fine and to be expected.  What surprised me and
took me a couple of hours to figure out was that busybox itself and not just
one of its symlinks was overwritten.  More specifically, here is what I think
happened in my case:

When busybox was built and installed, it was installed as /bin/busybox and many
symlinks including /sbin/init and /usr/sbin/flashcp were installed pointing to
/bin/busybox.

When mtd-utils was built and installed, flashcp was installed as
/usr/sbin/flashcp, but because a symlink already existed for busybox, the
symlink was followed and flashcp was actually installed as /bin/busybox
overwriting the real busybox in the process

When I booted the resulting rootfs, the kernel executed /sbin/init which should
have been busybox but was flashcp instead.  flashcp then complained about bad
command line arguments and exited cusing the kernel to panic because init
exited.

I'm new to buildroot, so if this is how things are supposed to work, I'll learn
to live with it.  In an ideal world, the config system would prevent such
overlaps in functionality.  I realize the large number of busybox options makes
that too tedious to be practical.  

Perhaps a reasonable middle solution is to make sure the installation of other
packages don't follow symlinks and clobber busybox.  Alternately, perhaps the
busybox installation can be deferred until after the other packages and its
symlink creation changed to not clobber existing files.

Ahh, ok - That's something completely else. I have updated the mtd-utils
package in git to 1.3.1, and fixed the target install to use 'install', which
doesn't follow symlinks.

Thanks.  I should have been clearer about the seriousness of clobbering busybox
the way it did.
