[Bug 1854140] [NEW] add an option to not strip filesystem prefix from file names

Wed Nov 27 08:46:50 UTC 2019

Public bug reported:

The filesystem prefix of the files in the main/ directory is not
preserved when an initrd is unpacked with unmkinitramfs.

If the initrd is rebuilt directly from main/ with cpio, the resulting
file won't work because links are invalid.

unmkinitramfs should have an option to not strip filesystem prefixes and
preserve the content of the archive..
