Another I forgot about: The default kernel RAM block device size is 4M. This is way too small for an uncompressed initrd image and will result in a "short write" (n of m bytes written, 0 < n < m) error message during boot[*]. To get around this, an rd_size=<xxx> option needs to be added to the kernel command-line, with <xxx> being a size (in K) large enough to hold the contents of an (uncompressed and unpacked) initrd directory tree. It's probably prudent to round this up generously (I had an initrd size of a little over 32M and used 65536 as size). [*] Somewhat amusing: Searching for this error message on the web yields all kinds of "no clue but have you tried ... ?" pieces of advice. The most original one I found was: "Open your computer, take out the DIMMs and put them back in again". _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
