I am attempting to extract a tarball (*.tgz, to be exact) and receiving terminal errors on extracted symlinks. Unfortunately, I cannot simply recreate the archive as this is a legacy archive for a system that no longer exists which was created before I was even out of high school (have to love working for a big company).
I have consulted the almighty Google; however all I can seem to find is information for excluding / following symlinks at creation time. The exact error I am receiving is something of a misnomer (error: read-only filesystem) and comes from the fact that a very large portion of the data payload is contained within numerous squash / cram / loop filesystems. The symlinks are referencing data within them which, obviously, cannot be mounted due to errors while extracting said tarball. Chicken; meet egg.
So, in short:
How can I extract a *.tgz archive to completion while either ignoring symlinks or ignoring resultant symlink errors?
