Ships a /etc/default/grub.d/45_debug-misc.cfg configuration file.
This removes quiet, loglevel=0, and rhgb from the
GRUB_CMDLINE_LINUX_DEFAULT variable. It also removes debugfs=off,
efi_pstore.pstore_disable=1, and erst_disable from the
GRUB_CMDLINE_LINUX variable. Finally, it adds debug=vc to the
GRUB_CMDLINE_LINUX variable to enable verbose output during the
initial ramdisk boot phase.
Undo debugging related sysctl settings by package security-misc-shared.
Enables persistent systemd journal log.
Disables /usr/lib/systemd/coredump.conf.d/30_security-misc.conf by package
security-misc-shared using debian/debug-misc.links by creating a symlink
from /etc/systemd/coredump.conf.d/30_security-misc.conf to /dev/null.
Disables /usr/lib/systemd/pstore.conf.d/30_security-misc.conf by package
security-misc-shared using debian/debug-misc.links by creating a symlink
from /etc/systemd/pstore.conf.d/30_security-misc.conf to /dev/null.
Disables panic-on-oops, remove-system.map by package
security-misc-shared.
config-package-dev hide /etc/sysctl.d/30_silent-kernel-printk.conf
which kernel.printk to default as if security-misc-shared would not have
lowered verbosity.
Configure systemd getty service to not clear tty.
/lib/systemd/system/[email protected]/30_debug-misc.conf
Coredumps are enabled.
/etc/security/limits.d/40_debug-misc.conf
Coredumps may contain important information such as encryption keys or
passwords. Package security-misc-shared disables coredumps. Package
debug-misc re-enables coredumps.
Contains a helper tool to cause a segfault for testing purposes.
segfault-build creates segfault-run. Running segfault-run results in
segfault-run terminating with a segfault. This is useful to test if
coredump files are being generated when an application crashes.
