In 990_verify_rootfs.sh fix issue #3021 (#3250)
|
|
|
|
In build/default/990_verify_rootfs.sh
|
|
for each 'not found' shared object
|
|
(i.e. a shared object that was 'not found' by 'ldd')
|
|
check whether or not the shared object
|
|
may exist nevertheless in the recovery system
|
|
and if yes, we may sufficiently safely assume
|
|
things are OK in the ReaR recovery system
|
|
so we do not report it as missing to the user
|
|
(for debugging we have all in the log), see
|
|
https://github.com/rear/rear/issues/3021#issuecomment-2165453757
|
|
Additionally in 990_verify_rootfs.sh
|
|
more consistent level when messages are shown,
|
|
i.e. now only LogPrint and LogPrintError
|
|
to show nothing (except errors) when not in verbose mode
|
|
and all messages when in verbose mode
|
|
to make the messages as a whole
|
|
better understandable by the user.
