...but becare full with these - you should keep them because they're |
| 33 |
really not defined on the above files and the getting the last one wrong |
| 34 |
will lead to the deletion of all files in distfiles...! |
| 35 |
|
| 36 |
The way the script work is first get the list of all sources related |
| 37 |
with the installed files from portache cache, merge it with the list of |
| 38 |
sources in distfiles, and delete those which are unique - i.e., only are |
| 39 |
in distfiles. There are two caveats with this procedure: |
| 40 |
- it will delete sources of packages in PORTAGE_OVERLAY, if you have |
| 41 |
any, since they aren't cached. |
| 42 |
- if the cache is busted (or can't be found), the most probable outcome |
| 43 |
is that all files in distfiles get deleted... so a good idea is to |
| 44 |
replace 'rm' by 'echo' to get an idea of what is gonna be deleted. |
| 45 |
|
| 46 |
These two caveats could be overcomed by getting the sources directly |
| 47 |
from the installed ebuilds, but that would be terribly slow compared |
| 48 |
with this, due to the parsing of all ebuilds. |
