Hello,
After installing guixsd (0.15) on a VM and doing "guix pull", "guix --version"
gives 0.14-<stuff>.
I asked about this on IRC a few weeks ago and got a helpful answer. All
I needed to do to fix is was to run a simple bash command.
Unfortunately, I've forgotten what that was :-(
Reporting here since I didn't find anything in the issue tracker when I
looked.
Thanks,
Alex

Hi Alex,

Yes, bash will not remember paths across reboots.

Bash optimizes lookups on the PATH; having found an executable on PATH
once, it can remember that location for a minor speed boost. The only
problem with this is that the cache can go stale.
>From what I understand remembering locations is usually done manually by
running “hash”. I don’t know what would trigger this behaviour in your
case.
