By convention, strstr should be a literal string match. Previously, it
would match as a glob pattern. Some code used that, so add new
functions strglob and strglobin to do what that code expects, and
specify them tightly too. strglob tests whether the glob pattern
matches the entire string (the name strglob is also used in the yorick
language, and that's what it does there), while strglobin tests whether
the glob pattern matches anywhere in the string.
Also tightens str_starts, str_ends, and str_replace to deal with
literal strings only. In a quick grep I did not find code that depended
on these functions matching globs.
Changes the call sites where strstr was used with glob patterns to use
strglobin or strglob as the intention seemed to be (or, in one case,
strstr with the * removed as it did not affect the result anyway).
We no longer require any user intervention when testing dracut on
a local block device in qemu, assuming everything passes. If things fail,
we still might need to manually kill things.
This creates a basic root filesystem, creates an initramfs, and tries
to boot to the basic filesystem.
The init code on the test filesystem prints how much memory is used vs. free
and then drops to a shell. Exiting the shell will power off the VM.
