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.
.

.
* 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.
