already-existing device nodes. This is done by invoking pax with its
current working directory set to an empty temporary directory.
* Add "-t mtree" command line option, to force MAKEDEV to use "mtree
-e -U" to create device nodes. Here are some timings from "MAKEDEV
${method} all" on an i386 system; each method was executed three
times, first in an empty directory, then twice in an already-populated
directory:
-m mknod
4.56 real 1.58 user 1.68 sys
2.96 real 1.37 user 1.48 sys
2.95 real 1.43 user 1.44 sys
-p pax
1.80 real 0.18 user 0.62 sys
2.35 real 0.25 user 0.80 sys
2.38 real 0.24 user 0.82 sys
-t mtree
1.62 real 0.22 user 0.44 sys
0.23 real 0.29 user 0.04 sys
0.24 real 0.28 user 0.05 sys
* If no command line options force a choice, then prefer mtree, pax, or
mknod, in that order of preference.
No objections in tech-userlevel to an earlier version of this change.
