Name
-bz
Synopsis
Prior to V8
sendmail the -bz command-line
switch caused sendmail to build (or rebuild) its
frozen configuration file (now obsolete). The frozen configuration
file was just a simple image of
sendmail’s variables after it
had read and parsed the configuration file. The purpose of the frozen
file was to enable sendmail to start up more
swiftly than it could when parsing the configuration file from
scratch.[9]
The -bz command-line switch is obsolete. If you
use it with V8 and higher sendmail, you will see
this error message:
Frozen configurations unsupported
[9] In practice, freeze files helped you only on systems with very fast I/O relative to their CPU speeds. Although this was true in the day of the VAX 11/750, improvements in processor technology have reversed this tradeoff.
