[PATCH] SDK: trap any IO errors in the relocate script

[PATCH] SDK: trap any IO errors in the relocate script

[Laurentiu Palcu]

If the files being relocated are already used by other processes the
relocate script will fail with a traceback. This patch will trap any IO
errors when opening such a file and gracefully report them to the user.

Also change the exit code from 1 to -1 for a better adt-installer user
experience (like pointing the user to the adt_installer.log).

This is what I usually use when I change single files. However,
sometimes (and I know this particular patch is not the case), I change
multiple files to fix a single problem or add a feature. In this case
your BKM is not quite appropriate. I will end up with a commit subject
like this:

filename1, filename2, filename3: <no space left for the subject itself>

If those files belong to a certain functional area, say SDK, I thought
it was more appropriate to prepend the subject with SDK.

Also, the contribution guidelines on the wiki, state the same (see rpm
example):

https://wiki.yoctoproject.org/wiki/Contribution_Guidelines

Am I wrong here?

Thanks,
Laurentiu

No but I think "SDK" is just a little unspecific so for example a hint
that this was a change to "scripts:"  would have been more useful which
I think was Saul's point.
