Here is some more information and related bugs on the issue:
Essentially, readlink() on /proc/self/exe will return the path of the
executable that calls it, but on an unionfs based system, it will return
the wrong path (/squashfs/usr/bin/mono). THe old patch simply commented
out the check on /proc/self/exe, which obviously was a bad idea, and
also causes random segfaults all over the place (currently evolution-
sharp is known to FTBFS due to this issue, f-spot also FTBFS if its
rebuilt after clearing its dependency issues).
THe replacement patch (which I'm now testing) checks the prefix of any
path read via the readlink /proc/self/exe function call, and then strips
off the bad section of the path as necessary.
As evolution-sharp is known to trigger this bug, my test will involve
building it once in a normal chroot jail, and building it again on the
liveCD with the replacement mono. It should success both times if mono
has properly been fixed.
