Re: [PATCH 1/2] sequencer: factor out rewrite_file()

I tried looking into this by adding a new write_file_buf_gently()
(or maybe renaming write_file_buf to write_file_buf_or_die) and
using it from write_file_buf() but I don't know the proper way to
handle the error-case in write_file_buf(). Just calling
die("write_file_buf") feels ugly, as the real error was already
printed on screen by error_errno() and I didn't find any function
to just exit without writing a message (which still respects
die_routine). Suggestions welcome.

How about *not* printing the error at the place where you notice the
error, and instead return an error code to the caller to be noticed
which dies with an error message?
