When it comes to system recovery on Linux, users are most often only left with a command-line for trying to recover from a failed kernel boot, borked boot loader configuration, or other show-stopping problems. With Fedora Workstation right now they have only their CLI-based Linux recovery process but are eyeing the possibility of creating a complementary GUI-based recovery environment...

GNU Compiler Collection developers are working towards the stable release of GCC 12 in the next month or so as GCC 12.1.

With Linux 5.18-rc1 released last night the merge window is now over for feature work on Linux 5.18. So as usual here is my feature overview of all the changes for Linux 5.18 that caught my eye and were interesting for this kernel that is working its way towards the stable debut by late May.

Building the Linux kernel with LLVM/Clang rather than GCC has continued maturing nicely since the support was mainlined two years ago and additional LLVM/Clang functionality continues to be optionally supported by the Linux kernel.
