Re: Bug#736198: undeterministic output when running egrep repeatedly with the same input



Bug is probably with kfreebsd-9 before 9.1, returning a wrong result to
lseek (fd, cur, SEEK_HOLE), which is used since grep 2.13:

Therefore this affects grep (and probably more things) in sid chroots on
wheezy host systems in conjunction with ZFS (likely true of Robert's
system and mine, but not the buildds).
