bug#38821: Can't run guix from external drive.

[Jan]

Hi,
I tried running "guix install" from my USB hard drive and that's what I
got:

user@machine /media/user/Backup$
Backtrace:

It most likely means that the current working directory,
/media/user/Backup, was unmounted or somehow disappeared in the
meantime.

Can you confirm that this is the case?

Thanks,

Yes, it only happens, if the disk is unmounted. Is that normal? If it
is, then a message telling what's wrong would be helpful.

This issue is not specific to Guix: the ‘getcwd’ function fails if the
current working directory has been unmounted behind the back of the
calling process.  IOW, another program would fail similar in these
circumstances.  I don’t think there’s much that can be done.

Thanks,
