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