comment Login without running bash_profile or bashrc
This is also true for sftp - even SSH subsystems are apparently executed from within a shell.

comment How does Duplicity check for modifications (mtime or checksum)?
Unfortunately, it's hard to find a proper test case, but I'll try to find one. Thanks for the hint with rsync-options!

That's impossible - Amazon S3 and even IMAP are storage options for duplicity, and there is no rsync available on either.

Will that work with duplicity's architecture? There is no "intelligent" rsync at the remote end; does it store the checksums in an index tar archive for that purpose? Or will it have to read the backup files in over the network to determine the checksums of the remote files?

comment Unzipping files that are flying in through a pipe
Nice one-liner, and +1 for mentioning that the file has to fit into memory. (There is unfortunately no way to unzip a pkzip file due to the file format structure).

comment What is the motivation for DNS64?
I see, so a host will always try to contact a remote host by the address family that has been returned by the DNS lookup, but fail if there is no corresponding interface available? Does that also mean that an IPv4-only application (e.g. one with hard-coded IP literals) will never be able to work on an IPv6-only host (at least not without any modifications to the network stack)?

So when an IPv6-only host receives an A reply, it doesn't try to contact the IPv4 address over IPv6 (by encapsulating it into an IPv6 packet, like 0::de:ad:be:ef:0...:0? The gateway could then change the header to IPv4 and do the NAT translation. Wouldn't that be an easy way to implement IPv6 to IPv4 connectivity?
