The test for the ability to decompress zisofs encoded files is supposed to fail due to the lack of this ability in GRUB. But it fails early with xorriso : FAILURE : -volid: Text too long (1650 > 32) because "ziso9660" is not in the list of filesystems which accept at most 32 bytes in their FSLABEL. If this is fixed, the test returns false success because the xorriso run does not produce any zisofs compressed files. The problem is in the sequence of native xorriso commands used. The command -set_filter_r applies only to the files which are already inserted into the emerging ISO filesystem. In the current sequence no files have been inserted yet by command -add when the last of two -set_filter_r commands is executed. After this is corrected, xorriso refuses to work because the global settings of command -zisofs can be made only before command -set_filter_r has attached zisofs filters to the data files in the emerging ISO. Further: A bug in xorriso causes a false warning about FSLABEL being too long for Joliet. Shortcomings of Joliet cause warnings about symbolic links. Such warnings might distract from the actual reason why the test is expected to fail. So, add "ziso9660" to the 32-byte FSLABEL list. Fix the xorriso run to produce compressed files which for now cause righteous failure of the test. Do this by removing a surplus group of -set_filter_r and -zisofs commands, by moving the other such group behind -add, and by swapping -set_filter_r and -zisofs. Remove the -as mkisofs options which produce a Joliet filesystem tree. Signed-off-by: Thomas Schmitt <scdbackup@gmx.net> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com>
This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. See the file MAINTAINERS for information about the GRUB maintainers, etc. If you found a security vulnerability in the GRUB please check the SECURITY file to get more information how to properly report this kind of bugs to the maintainers. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
