Using pmbootstrap v3 with the old config can cause problems, for example when having $WORK in the pmaports dir instead of the actual work path. This is not supported anymore by v3 to reduce complexity. The format of how mirrors are stored in the config also has changed. Use a separate config file, so users can go back from v3 to 2.3.x if they need to (for figuring out a regression) and so users won't run into bugs when moving from 2.3.x to v3.

"""This file constructs the args variable, which is passed to almost all
|
|
functions in the pmbootstrap code base. Here's a listing of the kind of
|
|
information it stores.
|
|
|
|
1. Argparse
|
|
Variables directly from command line argument parsing (see
|
|
pmb/parse/arguments.py, the "dest" parameter of the add_argument()
|
|
calls defines where it is stored in args).
|
|
|
|
Examples:
|
|
args.action ("zap", "chroot", "build" etc.)
|
|
args.as_root (True when --as-root is passed)
|
|
...
|
|
|
|
2. Argparse merged with others
|
|
Variables from the user's config file (~/.config/pmbootstrap_v3.cfg) that
|
|
can be overridden from the command line (pmb/parse/arguments.py) and
|
|
fall back to the defaults defined in pmb/config/__init__.py (see
|
|
"defaults = {..."). The user's config file gets generated interactively
|
|
with "pmbootstrap init".
|
|
|
|
Examples:
|
|
args.aports ("$WORK/cache_git/pmaports", override with --aports)
|
|
args.device ("samsung-i9100", "qemu-amd64" etc.)
|
|
get_context().config.work ("/home/user/.local/var/pmbootstrap", override with --work)
|
|
|
|
3. Parsed configs
|
|
Similar to the cache above, specific config files get parsed and added
|
|
to args, so they can get accessed quickly (without parsing the configs
|
|
over and over). These configs are not only used in one specific
|
|
location, so having a short name for them increases readability of the
|
|
code as well.
|
|
|
|
Examples:
|
|
deviceinfo (e.g. {"name": "Mydevice", "arch": "armhf", ...})
|
|
