- Log the error message (and the line causing the error) to console
- Log the whole exception (with some excess junk removed) to debuglog
- don't immediately SystemExit if the template won't parse
- clean up some comments
This lets us easily do whitelisting instead of blacklisting during
runtime cleanup. For example:
removefrom xfsprogs --allbut /sbin/* /usr/sbin/xfs_admin
would remove everything from the xfsprogs package except files in /sbin
and /usr/sbin/xfs_admin.
A few things in runtime-cleanup have been converted to use --allbut. The
only difference in the created runtime image is that we're deleting
/usr/share/kde4 from fedora-logos.
make sure that runner.templatedir gets set to a useful default if
initialized with None, and and make sure we pass templatedir to
LoraxTemplateRunner.__init__ (so it'll get initialized properly)
emit a useful log message if we attempt to removepkg something that
isn't installed, or if a glob used in a removefrom line matches no
files.
this will help us keep the templates cleaner.
getdata(cmd) will return a generator that yields every token on every
line that starts with the token "cmd". getdata(cmd, mode="lines") will
yield a list for each line rather than every individual token.
this simplifies some things in __init__.py.
