Gents,
I still have a few packages where the included pdf has a creation/mod time
stamp that differs. I am __almost__ at the point where I can override the
created pdf file:
- it works in a normal shell, ie the sequence
pdfinfo somefile.pdf
fixTimestamps.sh somefile.pdf 'timestamp_from_debian/changelog'
pdfinfo somefile.pdf
works: the file remains valid, and pdfinfo shows the before/after
timestamps as desired
- it does NOT work in pbuilder and I cannot narrow down why -- the second
pdfinfo call (added for debugging) reports a corrupted pdf file.
To be clear, I use the same exact helper script: it works 'on the shell' but
not in pbuilder. What am I missing?
The script-let (in its current form) is below.
