Re: [Ltib] LTIB query

[Stuart Hughes]

Hi Gernot,

Just a bit of background information on %ldirs.  Although it can be used
to provide a way of users storing their own content, it's not intended
for that.

The purpose of %ldirs was mainly to provide a backward compatible way of
 supporting older LTIBs without having to re-duplicate downloaded
content.  If you look at the setting you see:

1. /var/tmp/pkgs
2. /opt/freescale/pkgs

1. Was the really really old place that LTIB stored downloaded content.
 It was chosen as it was open to write by all users.  It soon got
discarded as I forgot tmpwatch (Fedora) will clean this area up if a
file hasn't been accessed for x amount of time.

2. This is where Freescale BSPs download to, it's still current.  I
wanted to separate the Savannah/Freescale download areas, but not to
re-downloaded if content was present in /opt/freescale/pkgs, so that's
why this is in %ldirs

Now back to the original point.  It's best not to extend %ldirs without
care, for example as a per-user storage (supported by multiple dirs).
The reason is that you could end up with:
        * duplication of content
        * filename clashes (2 files of same name in different area)
You could legitimately use %ldirs in a controlled way if you added one
directory that you were going to use say for your own original (possibly
sensitive/proprietary) content.

Regards, Stuart
