[Jfs-discussion] mkfs.jfs options

[Peter W. <pw...@gw...>]

I am interested to know a bit more about mkfs.jfs options, especially
"-O". The manpage just says
   Provide case-insensitive support for compatibility with OS/2.
so I used this when I installed Gentoo Linux 2004.1, using the 2.6.5
kernel, because I would like access this partition when I booted OS/2.

But when I do this, the emerge command does not work, giving the
following error:

     $ emerge development-sources
     /usr/lib/python2.3/fcntl.py:7: DeprecationWarning: the FCNTL module is deprecated; please use fcntl
       DeprecationWarning)
     Calculating dependencies
     !!! Problem in sys-kernel/development-sources dependencies.
     !!! 'module' object has no attribute 'flock'

I guess "fcntl" and "flock" refer to file-system locking mechanisms that
are somehow not working when I use mkfs.jfs -O. Is this intentional? Are
there other side effects of using "-O"?

Cheers,
   Peter.
