-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Format: 1.8 Date: Tue, 24 Nov 2015 12:38:06 +0100 Source: makedumpfile Binary: makedumpfile kdump-tools Architecture: all amd64 source Version: 1:1.5.9-1 Distribution: sid Urgency: medium Maintainer: Louis Bouchard <louis.bouch...@ubuntu.com> Changed-By: Louis Bouchard <louis.bouch...@ubuntu.com> Description: kdump-tools - scripts and tools for automating kdump (Linux crash dumps) makedumpfile - VMcore extraction tool Changes: makedumpfile (1:1.5.9-1) sid; urgency=medium . * New upstream version includes : o Parallel compression - Add the new option "--num-threads" to enable parallel compression for faster processing. This option intends parallel compression while --split intends parallel i/o, they try to solve different bottlenecks. . o Change the way to choose the non-cyclic mode - Add the new option "--work-dir" to specify the directory used to store the bitmap. This is the alternative to the combination of --non-cyclic and TMPDIR. . o Support new kernels - The supported kernel is updated to 4.2 in this version. .

(by Atsushi Kumagai) 3ef6629 . * Debian specific enhancements : . - kdump-tools now make use of smaller initrd.img files created in /var/lib/kdump. This avoid optential OOM when the size of the initrd.img becomes larger (LP: #1496317). Implementation details are : . o New kernel hooks are added to create smaller initrd.img files when new kernel packages are installed : /etc/kernel/postrm.d/kdump-tools /etc/kernel/postinst.d/kdump-tools . o kdump-config is responsible for the maintenance of symbolic links used to point to the appropriate vmlinuz & initrd files. Link maintenance is done at each boot by kdump-config. New links will point to the files named after the running kernel. . o The KDUMP_KERNEL and KDUMP_INITRD configuration variables are now now enabled and use the symbolic links : /var/lib/kdump/vmlinuz /var/lib/kdump/initrd.img . o kdump-config has been adapted to show the symbolic link information . - kdump-tools is now enabled by default. When installed a prompt will propose to override the default value.
