1 the [[plugins/aggregate]] plugin mashes the `title` of an aggregated post into a filename. This results in long filenames. I have hit a filesystem length limitation on several occasions. Some (ab)uses of RSS, e.g., twitter,
2 generate long titles. Especially once you throw escaping into the mix:
4 $ ikiwiki --setup testsetup --aggregate --refresh
5 failed to write ./test/lifestream/Hidden_Features_Of_Perl__44___PHP__44___Javascript__44___C__44___C++__44___C__35____44___Java__44___Ruby___46____46____46__._aggregated.ikiwiki-new: File name too long
6 aggregation failed with code 9216
10 It would also appear this abrubtly terminates aggregate processing (if not ikiwiki itself). Only after moving my test repo to `/tmp` to shorten the filename did I see newer RSS feeds (from a totally different source) picked up.
