Introduce a new "cache" subdirectory in the pmbootstrap workdir, all the cache and config bits go in here, anything that needs to be accessible from inside a chroot. The whole dir is then bind-mounted into the chroot as /cache with appropriate symlinks. This dir is in the config as config.cache. In addition, all the cache_* and other config dirs are renamed to be closer to the names of the equivalent dirs in the chroot (e.g. abuild-config) and to avoid redundant naming since they are now under a "cache" dir.

"""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/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", ...})
|
|
