   4 Subject: [PATCH] os-prober: Allow initrd to contain spaces
   5
   6 linux-boot-prober produces structured output with newline-terminated rows
   7 representing kernels, each with colon-delimited columns. We translate
   8 this into a sequence of space-separated words representing kernels,
   9 each containing colon-delimited fields where spaces are represented by
  10 carets.
  11
  12 When we parse each of those words into colon-delimited fields, if the
  13 field could conceivably contain spaces then we need to translate
  14 carets back into spaces. We did this for label and parameters, but not
  15 for the initrd.
  16
  17 In particular, when CPU microcode is installed on Arch Linux or its
  18 derivatives, they write CPU microcode into one initrd archive and the
  19 rest of early user-space into another, instead of concatenating the
  20 archives into a single file like Debian derivatives do. To boot Arch
  21 successfully from the grub menu, we need to add all of their initrds
  22 to the grub menu entry (detecting this situation requires an os-prober
  23 patch, for which see <https://bugs.debian.org/820838>).
