Hi! > At this moment unionfs has got at least following problems: > 1) File systems cannot mount onto upper/lower unionfs layer (partially > described in kern/117829) I tested your patch as described in http://lists.freebsd.org/pipermail/freebsd-stable/2007-June/035798.html and /dev works for me now. Nice work! > 2) There are problems with multithreaded programs accessing(writing) files > on unionfs (kern/109950) > 3) As well there are problems with accessing unix sockets created on > upper/lower unionfs layers (kern/118346) > 4) Doing mv filename same-filename causes kernel to panic on 6.X (and > printing warning about VOP_RENAME in 7+) I tested this bug on a 6.3-REL with a 6.2 unionfs (20070213) and it does not panic. I tested it on a 6.3-REL with your patch and did also did not panic. So, from my point of view, it's an improvement. -- pi@opsec.eu +49 171 3101372 12 years to go !
