the first run of update.sh sets up a cron job to run itself
periodically. the update script takes one position argument, the git
branch to pull changes from, which is also known as "sysupdates channel"
- master for stable, dev for testing.
the sysupdates channel was lost in the cron job setup, always defaulting
to master (stable). this commit preserves the original arg value given
to update.sh during the initial run.
when testing upcoming changes on a live node, it is desirable to turn
off automatic updates simply by removing the x file permissions bit.
this commit makes sure the x bit is set only for newly created file.
extract from upstream release notes:
- bug has been fixed where the responder of a zero-conf channel could forget
about the channel after a hard-coded 2016 blocks
- bug where LND wouldn't send a ChannelUpdate during a channel open has been fixed
- bug has been fixed that caused fee estimation to be incorrect for taproot
inputs when using the SendOutputs call
- bug has been fixed that could cause lnd to underpay for co-op close transaction
when or both of the outputs used a P2TR address
