We can infer from ProcMaps when LD_* libraries were used to load
libraries from e. g. /usr/local or /home. The generic hook already does
that check and tags a bug with "local-libs" if that happens:
------------------ 8< --------------------
# using local libraries?
if 'ProcMaps' in report:
local_libs = set()
for lib in re.finditer(r'\s(/[^ ]+\.so[.0-9]*)$', report['ProcMaps'],
re.M):
if not apport.fileutils.likely_packaged(lib.group(1)):
local_libs.add(lib.group(1))
if local_libs:
if not ui.yesno('''The crashed program seems to use third-party or
local libraries:
%s
It is highly recommended to check if the problem persists without those
first.
Do you want to continue the report process anyway?
''' % '\n'.join(local_libs)):
raise StopIteration
report['LocalLibraries'] = ' '.join(local_libs)
report['Tags'] = (report.get('Tags', '') + ' local-libs').strip()
------------------ 8< --------------------
Is that sufficient for your purpose?
What do you want to get out of $DISPLAY, just knowing that it's set? The
particular value probably isn't very interesting?
