Subject: [PATCH] os-prober: Allow initrd to contain spaces
linux-boot-prober produces structured output with newline-terminated rows
representing kernels, each with colon-delimited columns. We translate
this into a sequence of space-separated words representing kernels,
each containing colon-delimited fields where spaces are represented by
carets.
When we parse each of those words into colon-delimited fields, if the
field could conceivably contain spaces then we need to translate
carets back into spaces. We did this for label and parameters, but not
for the initrd.
In particular, when CPU microcode is installed on Arch Linux or its
derivatives, they write CPU microcode into one initrd archive and the
rest of early user-space into another, instead of concatenating the
archives into a single file like Debian derivatives do. To boot Arch
successfully from the grub menu, we need to add all of their initrds
to the grub menu entry (detecting this situation requires an os-prober
patch, for which see <https://bugs.debian.org/820838>).
