I tried to replicate tis error on Ubuntu 10.4 using a private mlocate
database:
updatedb -l 0 -o db_file -U 1wire
But it completes successfully. Indeed, I've run an (older) version of owfs
and updatedb for years at a time.
There are clearly differences in our setup.
For starters, can you give:
owfs invocation command line
A directory listing of your 1wire directory.
/opt/owfs/bin/owfs -V
updatedb -V
Thanks,
Paul Alfille
