similar to: [PATCH] kinit.c:get_arg()

A patch for a few more hiccups and trivialities in kinit.c: * The check_path() calls check for "/root" and "/old_root" - I believe that should be "/root" and "/root/old_root". * chdir("/") is recommended after pivot_root() * init_argv[0] isn't set properly to the basename pointed to by char *s - this fix also eliminates six lines of

I'm wondering where things are on the roadmap for klibc and initramfs/early userspace. When will everything be harmonized with the kernel and be the default? What is left to do? I'm in my own little world, but I have a pretty good klibc/hotplug/udev/kinit early userspace that just works (for me). It's taken me a bit to get things to work because I just couldn't find all the

When using the kernel command-line, the following format is required: 'kinit_mount=<fs_name>;<fs_dir>;<fs_type>;<fs_opts>' Multiple mount options can be specified; they are evaluated in the order they appear in the command-line.

initramfs-tools wants to validate the real init program before running it, as there is no way out once it has exec'd run-init. This is complicated by the increasing use of symlinks for /sbin/init and for /sbin itself. We can't simply resolve them with 'readlink -f' because any absolute symlinks will be resolved using the wrong root. Add a dry-run mode (-n option) to run-init
