Description of the issue (ideally so that others can reproduce it): Running
rear mkbackuphangs on /usr/sap/trans NFS mountpoint when it tries to locatefind /usr -name menu.c32 -
Workaround, if any:
Edit file
/usr/share/rear/lib/bootloader-functions.sh
file=$( find /usr -name "$1" 2>/dev/null | tail -1 )
change into:
file=$( find /usr -xdev -name "$1" 2>/dev/null | tail -1 )
When we run rear mkbackup again we see in the logs:
