4 # This file requires sysutils/makefs to run
6 # The PicoBSD build script. Invoked as
8 # picobsd [options] image_type [site_name]
10 # Where image_type is a directory with the picobsd config info,
11 # and ${image_type}/floppy.tree.${site_name} contains
12 # optional site-specific configuration.
14 # For Options, see the bottom of the file where the processing is
15 # done. The picobsd(8) manpage might be of some help, but code and docs
16 # tend to lose sync over time.
18 # This script depends on the following files:
21 # Makefile.conf Makefile used to build the kernel
22 # config shell variables, sourced here.
23 # mfs.mtree mtree config file
24 # floppy.tree/ files which go on the floppy
25 # mfs_tree/ files which go onto the mfs
28 # PICOBSD kernel config file
29 # config shell variables, sourced here.
30 # crunch.conf crunchgen configuration
31 # mfs.mtree overrides ${PICO_TREE}/mfs.mtree
32 # floppy.tree.exclude files from floppy.tree/ which we do not need here.
33 # floppy.tree/ local additions to ${PICO_TREE}/mfs_free
34 # floppy.tree.${site}/ same as above, site specific.
35 # mfs_tree/ local additions to the mfs_free
36 # buildtree.mk optional Makefile to build an extension for floppy tree
37 # (generated in buildtree/ )
40 #--- The main entry point is at the end.
43 # There are two initialization functions:
46 # is run on entry to the script, and is used to set default values
47 # for all variables that do not depend on image type and source tree.
49 # + set_build_parameters
50 # is run after command line parsing
53 # + variables that control operation (e.g. verbosity) and are generally
54 # set from the command line have o_ ("option") as a name prefix
56 # + variables that contain pathnames and values that should not change
57 # have c_ ("constant") as a name prefix
59 # + variables exported to Makefiles and subshells are CAPITAL
61 # + variables local to the script are lowercase, possibly with
62 # an l_ ("local") prefix.
64 # There are unfortunately exceptions:
65 # name, l_usrtree, l_objtree
67 # SRC points to your FreeBSD source tree.
68 # l_usrtree points to the /usr subdir for the source tree.
69 # Normally /usr or ${SRC}/../usr
70 # l_objtree points to the obj tree. Normally ${l_usrtree}/obj-pico
71 # c_label is either bsdlabel or disklabel
72 # PICO_TREE is where standard picobsd stuff resides.
73 # Normally ${SRC}/release/picobsd
74 # You can set SRC with --src <directory>
75 # It is not recommended to override the other variables.
77 # MY_TREE (set later) is where this floppy type resides.
