Hi,
I installed a new version of GNU coreutils (9.3), and now "shuf" appears
to be blocking on Linux's cryptographic RNG init. On this particular
machine, there is not a lot of entropy sources so Linux's RNG init takes
an unbounded and potentially very long time.
I hope nobody expects "shuf" to
I suppose that might be hard to do in this /particular/ case, as it
looks like the error is coming from a make rule. The Autoconf manual
quite emphatically says to avoid 'for arg; do ...' by using a newline
instead of a semicolon, a feat which is not easily done in make rules.
Cheers,
