RE: ipkg 0.116

Just For Completeness in the familiar ipkg.comf
There is the line

dest ext /mnt/hda

of cource that's ok when I install my C/F Card
but when its not installed the list file is on the internal Filesystem

I read about a "union mount" or transparent mounts in other Unix's BSD
??
 
http://www.ussg.iu.edu/hypermail/linux/kernel/9911.2/0350.html

would this be an alternative ???

It's a pity you cannot do (as a path not a variable)

$QTDIR = /Opt/QtPalmtop;/mnt/hda/QtPalmtop

        Ah, I see ...

        Well that I do not know. I only know it DOES put the INSTALL
path
        in the list file. That already before my patch the case

        renaming paths or dirs ALWAYS creates problems and always needs
workarounds
(like creating a link to the old mountpoint) Again it would be better
to use
logical mountpoint names (much like what is needed for devfs)

        If you move mount points I would always suggest creating a link
pointing from
the old dir to the new dir (or better NOT depend on physical mount
points
altogether)

        What can I say ... ipkg does it this way. I just noticed that
it stored
these paths in an absolute way. I do not know the reason for this
decision
only a solution to some ipkg bugs.
