About

Grml is a Debian based live system focusing on the needs of system administrators. This Grml release provides fresh software packages from Debian testing (AKA bullseye). As usual it also incorporates up to date hardware support and fixes known bugs from previous Grml releases.

Important Changes

• The default mount point for the live system was changed from /lib/live/mount/medium to /run/live/medium. This works around a regression which appears on-again-off-again, and follows upstream changes for Debian/bullseye. If you don't have any custom tools which rely on /lib/live/mount/medium (or its ancestor /live/image), then this change is irrelevant for you.
• Tools like grml2usb, grml-paste and grml-x have been ported from Python2 to Python3 (AKA py3k), we no longer support Python2 in our tools.
• The live system no longer uses a custom Grml kernel, instead we switched to the linux-image packages provided by Debian.

New features

Highlighting the most relevant changes only:

Misc:

• cloud-init support (grml-full only): cloud-init is a standard multi-distribution method for cross-platform cloud instance initialization. Cloud-init identifies the cloud it is running on and reads any provided metadata from the cloud and initializes the system accordingly. This is useful for e.g. setting network configuration, SSH access key and hostname. To enable it on Grml, boot with boot option `services=cloud-init`. If you configured a SSH public, logging in as user `grml` works. For static network configuration you need to boot with boot options `nonetworking services=cloud-init,networking`.
• qemu-guest-agent support: when running in appropriate environments (like Proxmox VE) this daemon exchanges information between the host and guest system (VM) (also see Proxmox wiki for further information). When booting Grml as a VM in such an environment, the network information is visible in the VM summary then, like:

• network information in grml-quickconfig: hostname, cloud-init, IP addresses and zeroconf/avahi information:

grml-live (build system for creating Grml (based) Linux live systems):

• Support for cloud-init (via GRML_FULL)
• sudoers: set Defaults secure_path to have sane default settings
• initramfs xz-compress: use default xz compression level
• GRMLBASE/98-clean-chroot: fix resolvconf symlink handling + get rid of resolvconf workarounds
• Rebuild /var/lib/dpkg/available to install not-yet-installed packages in update runs
• Sources list setup for security: switch from testing/updates to testing-security
• Switch default mount point from /lib/live/mount/medium to /run/live/medium
• Provide boot menu for Predictable Network Interface Names

grml2usb (tool to install Grml ISO to usb device):

• Support more syslinux module locations and support setting custom ones via option --syslinux-libs=...
• No longer explicitly list addon files, instead copy all files from /boot/addons/
• Provide git-describe based version information when running from within git
• Fix path to syslinux *.c32 files
• Add smoke autopkgtests to Debian packaging
• Abort if required logo.16 file is missing
• Avoid custom boot options getting duplicated when used with multiple ISOs
• grml2iso supports EFI boot

grml-hwinfo (tool to collect hardware information):

• Store output of `lscpu -e` in file `lscpu_extended`
• Store cpuid output in file `cpuid`, add cpuid to Recommends
• Record uptime (/proc/uptime in `proc_uptime` and uptime(1) in file `uptime`)
• Report SecureBoot state via mokutil
• Store "$HOME"/.local/share/xorg/Xorg.0.log (if available) as user_Xorg.0.log
• Log output of verbose lsusb run in file lsusb_verbose
• Provide output of verbose lspci run in file lspci_verbose
• Recommend acpica-tools package and provide acpidump output (as root)

grml-zshrc (Zsh configuration):

• Add zstd support to simple-extract()
• Reset $REPLY parameter before calling prompt token functions
• Disable bracketed paste mode for dumb terminals
• Fix urxvt multi-line issue
• commit-to-history: keep escaped character
• Support PAGER='less -Mr' usage and fall back to vi if LESSOPEN is unset

grml-debootstrap (wrapper around debootstrap for installing pure Debian):

• Add support for .ssh/authorized_keys via cmdline option --sshcopyauth
• Support BOOT_APPEND usage outside of VMs
• Support mmdebstrap via DEBOOTSTRAP=mmdebstrap
• Use new security.debian.org repository layout for bullseye and newer
• Fix detection of predictable network interface names
• Add option --sshcopyid to authorise root login
• Provide workaround for Debian bug #918590 with LVM + udev in VM installations
• /etc/fstab: provide header comment, pointing to man pages and systemctl daemon-reload
• Add DHCP setting for Predictable Network Interface Names

Bits & bolts

• Linux kernel 5.6.
• Fixed several bugs from the issue tracking system.
